Senate Majority Leader Mitch McConnell (R-Ky.) appeared Wednesday on The Daily Briefing to reflect on Tuesday's midterm elections.

He said that Republicans "had a great day" after growing their majority in the Senate, and despite losing the House to Democrats.

He reiterated a suggestion to the new Democratic House majority that potentially "harassing" the president wouldn't' be a smart idea.

"The business of presidential harassment might not work out too well for you politically," he said, referring to possible investigations of the administration.

He said that attacks on health care or Social Security by the GOP were a "Democratic fantasy" in response to remarks made by Rep. Nancy Pelosi (D-Calif.)

In a news conference on Wednesday, Pelosi said that voters on Tuesday "went in a new direction" and "delivered a resounding verdict against congressional Republicans' attacks on Medicare, Medicaid, and the Affordable Care Act and people with pre-existing conditions."

McConnell also said that incumbent Senate Democrats who voted against Supreme Court Justice Brett Kavanaugh made "a mistake" in doing so.

Senators Heidi Heitkamp (N.D.), Joe Donnelly (Ind.), Claire McCaskill (Mo.) and Bill Nelson (Fla.) all suffered defeat on Tuesday.

"It ended up politically being a godsend for Republicans," McConnell said.
