The White House ruled out Thursday making a former American diplomat or others available to Russian interrogators, the latest in a series of reversals since President Trump's summit on Monday with his Russian counterpart in Helsinki.

A pyrotechnic week of geopolitical intrigue has yielded new clarity about the whys and wherefores of the Russia imbroglio, including one insight straight from Russian President Vladimir Putin.

Why did Putin order the campaign of "active measures" that have been directed against the United States and the West since before the 2016 election?

Charges accusing a woman of trying to build bridges between the Russian government and American political leaders via the National Rifle Association have delivered a breakthrough in understanding one aspect of the attack on the 2016 election: "infiltration."

This week in the Russia investigations: Six insights about the latest master blast from special counsel Robert Mueller.

The big one

As the noted counterintelligence analyst Kenny Loggins once said: "This is it."

Updated at 9:38 p.m. ET

The Justice Department charged 12 Russian intelligence officers on Friday with a litany of alleged offenses related to Russia's hacking of the Democratic National Committee's emails, state election systems and other targets in 2016.

Deputy Attorney General Rod Rosenstein, who announced the indictments, said the Russians involved belonged to the military intelligence service GRU. They are accused of a sustained cyberattack against Democratic Party targets, including its campaign committee and Hillary Clinton's campaign.

This week in the Russia investigations: "Please don't interfere!" Senate Republicans tell Moscow. Peter Strzok heads back into the lion's den. Is Mueller farming out work? The Senate intel committee supports the intelligence community.

"Putin's fine ... We're all fine"

Members of a Republican delegation to Russia over the Independence Day holiday said they made a clear request of their hosts: Don't attack any more American elections.

This week in the Russia investigations: President Trump's nominee for the Supreme Court could play an important role down the road in the Russia imbroglio.

Freefall

Nearly two years into the international hall of mirrors that is the Russia imbroglio, one thing has remained constant: There is no way to know what new madness each sunrise might bring.

In campaign season, eventually the election takes place, new public officials are installed, and life moves on. When legislators try to govern, they either pass the bill or don't, and life moves on.

A senior FBI investigator whose personal opposition to Donald Trump has become a huge public embarrassment for the Justice Department made a marathon visit to Congress on Wednesday.

Deputy Assistant FBI Director Peter Strzok talked for several hours behind closed doors with the House Judiciary Committee. The committee issued a subpoena to compel him to appear even though Strzok had said he would speak voluntarily.

This week in the Russia investigations: A Justice Department report impacts Washington like a meteor; the inspector general confirms the presence of likely fraudulent intelligence; a special agent's words could be a political gift to President Trump.

Aftermath

Justice Department Inspector General Michael Horowitz has painted his masterpiece.

Updated at 11:06 a.m. ET

The Justice Department's internal watchdog agency unveiled a doorstop-sized report Thursday that provides an inflection point — but no closure — in the never-ending war over the 2016 presidential campaign and its aftermath.

The Russia imbroglio is a tale told out of order about a puzzle with pieces missing. Without knowing what goes in the blank spaces, it's impossible to know what to make of the whole thing.

The broadest outline has become clear: Russian President Vladimir Putin sought vengeance against the United States and the West after what he perceived as an outrageous overstep by Washington, D.C., into his own front yard in 2014 after Russia's invasion of Ukraine.

Updated at 10:35 p.m. ET

Prosecutors unsealed more charges on Friday against Donald Trump's former campaign chairman Paul Manafort and also accused a new defendant of conspiring with Manafort to obstruct justice.

Prosecutors allege that a Russian partner of Manafort's, Konstantin Kilimnik, helped him try to persuade witnesses to lie to the jury when Manafort's case comes to trial in Washington, D.C., this autumn.

The Justice Department's internal watchdog is set to release a hotly anticipated report next week that is expected to condemn department leaders and the FBI over the investigation during the 2016 presidential campaign into Hillary Clinton's private email server.

The Russia imbroglio has brought Washington, D.C., to a crossroads that could have historic implications for President Trump and the nation.

Justice Department special counsel Robert Mueller wants to interview Trump about what he knows and why he has acted in the way he has. The president and his attorneys have all but ruled that out. The president denies any wrongdoing.

Which side will blink?

This week in the Russia investigations: If "collusion" is now fully partisan in the House, the Senate and the public, that is good news for the president.

The politics of the Russia imbroglio took a little-noticed but important break last week for President Trump and the White House.

Updated at 10:19 a.m. ET

President Trump resumed his attacks against Attorney General Jeff Sessions on Wednesday following reports that he had asked Sessions to un-recuse himself from the Russia investigation — and after more erosion of Trump's claim that the FBI spied on his campaign.

Trump used his Twitter account to echo the comments of House oversight committee chairman Trey Gowdy, R-S.C., who has been using TV appearances to try to offer some nuanced support to Trump.

This week in the Russia investigations: After Trump's "SPYGATE" gambit, what just happened? Good news for Kushner. Mueller to hacks: Get lost.

What just happened?

President Trump or his supporters make an explosive allegation. Washington, D.C., responds with an uproar. An "investigation" ensues. Turns out, the allegations weren't what they appeared.

Updated at 2:12 p.m. ET

President Trump intensified his attack on federal law enforcement as he sought to strengthen his case that the FBI's investigation into whether his campaign conspired with Russia actually amounted to unlawful political snooping.

"I hope it's not so, but if it is, there's never been anything like it in the history of our country," the president said Wednesday.

Updated at 4:16 p.m. ET

Key congressional leaders are set to meet Thursday with federal law enforcement and intelligence bosses amid a slow-motion standoff over secret documents in the Russia investigation, the White House said on Tuesday.

Press secretary Sarah Sanders said that the White House had brokered a meeting at which two key Republican chairmen would hear from the leaders of the Justice Department, FBI and the intelligence community following weeks' worth of requests for the classified material.

This week in the Russia investigations: The Senate Judiciary Committee dumps documents about the 2016 Trump Tower meeting, the special counsel's office celebrates its first birthday and the GOP escalates its war against the Justice Department.

The enemy within

After chapters on "wiretaps," eavesdropping, "unmasking" and the Foreign Intelligence Surveillance Act, the new hotness this week was confidential sources.

Updated at 9:42 a.m. ET

Thursday marks one year since the appointment of Justice Department special counsel Robert Mueller. Has any public figure in the United States ever become such a partisan lightning rod after having said so little?

The Senate Judiciary Committee unleashed a new tranche of records on Wednesday that offered the most detail yet about one of the most important subplots in the Russia imbroglio.

The more than 2,500 pages in the trove add the most context yet about the meeting that took place on June 9, 2016, in Trump Tower between top Trump campaign aides and a delegation of Russians after an offer of help in the contest against Hillary Clinton.

Updated at 11:59 a.m.

The Senate Judiciary Committee released more than 2,500 pages of documents on Wednesday related to its investigation about a meeting in 2016 between top Trump aides and a delegation of Russians who promised to help the campaign.

The material, which includes interview transcripts and other "exhibits," is available here.

This week in the Russia investigations: Enter Viktor Vekselberg. Who is helping Michael Avenatti? Oleg Deripaska's wings have been clipped — for now.

The Vekselberg matter

Energy baron Viktor Vekselberg has the reputation as a "nice" Russian oligarch.

An explosive document released Tuesday by an attorney suing President Trump and his personal lawyer could be the most important public evidence in the Russia imbroglio since Donald Trump Jr. released his emails last year.

Updated at 10:27 p.m. ET

Donald Trump's personal attorney, Michael Cohen, may have received hundreds of thousands of dollars in payments from both corporate clients and potentially a Russian billionaire, according to new allegations from an attorney suing them.

Michael Avenatti, who represents adult film actress Stormy Daniels, described what he called Cohen's suspicious financial relationships in a document released on Tuesday evening.

New York lawmakers will carry on trying to close a loophole that could shield people from state prosecution if they have received a presidential pardon — without the bill's high-profile champion, former state Attorney General Eric Schneiderman.

President Trump's newly aggressive stance toward special counsel Robert Mueller will be the biggest test yet of the work he and allies have carried on for months to shape the political landscape among their supporters.

Trump and his attorneys appear to be hardening their attitude toward Mueller's office as discussion continues swirling about a potential presidential interview — whether Trump should agree, or risk a subpoena, or fight it, or invoke his Fifth Amendment right not to give evidence.

This week in the Russia investigations: After a lot of Sturm und Drang, the door appears to be closing on an interview between President Trump and Justice Department special counsel Robert Mueller.

The long shot

At the conclusion of another outrageous dust devil week of news, here is the main thing to take away: An interview between President Trump and the team of Justice Department special counsel Robert Mueller now appears less likely than ever.

White House attorney Ty Cobb is retiring at the end of this month and veteran Washington lawyer Emmet Flood, who helped President Bill Clinton in his impeachment proceedings in the late 1990s, has signed on to replace him, the White House said Wednesday.
