Robert Pittenger

There was at least one big upset in North Carolina congressional primaries Tuesday: incumbent Robert Pittenger lost a close race to Republican Mark Harris, a challenger he beat by only 134 votes two years ago.

Challenger Mark Harris defeated incumbent Republican Congressman Robert Pittenger by a margin of 814 votes.

Mark Harris has become a familiar name on the Republican ballot in North Carolina. He ran for the U.S. Senate in 2014, losing to Thom Tillis. Two years ago, he lost to Robert Pittenger in the primary race for the 9th district in Congress by just 134 votes.

This year, Harris is back for another shot at Pittenger. Both say the circumstances are different and in their favor for next week’s primary.

As the debate over tariffs on Chinese products and a potential trade war intensifies, there’s another battle emerging.

It concerns a multi-governmental agency called CFIUS - the Committee on Foreign Investment in the United States. CFIUS reviews foreign purchases of American companies to make sure they don’t jeopardize national security.

But a bipartisan group in the U.S. House and Senate says the committee needs expanded powers. In the House, North Carolina Congressman Robert Pittenger is leading an effort to overhaul CFIUS.

All 13 of North Carolina's representatives in the U.S. House voted in favor of an overhaul of the country's mental health system Wednesday. The bill gained momentum this year in part because of mass shootings.
