THURMONT, Md. — President Donald Trump says he’s done campaigning for insurgents challenging incumbent Republican members of Congress.

Trump told reporters after meeting GOP House and Senate leaders at Camp David on Saturday that he’s planning a robust schedule of campaigning for the 2018 midterm elections and that includes involvement in the Republican primaries. He’ll campaign for incumbents, he said, and “anybody else that has my kind of thinking.”

But after a stinging loss in Alabama, Trump said he’s done supporting challengers, declaring: “I don’t see that happening.” Trump had supported Roy Moore after he won the GOP primary. Moore’s defeat in the subsequent special election handed Democrats another seat in the Senate.

Trump spent much of Friday and Saturday morning hashing out his 2018 agenda with GOP House and Senate leaders, top White House aides and select Cabinet members at the presidential retreat at Camp David. He described the sessions as perhaps transformative in certain ways.”

A long list of high-stakes topics were on the agenda, from national security and infrastructure to the budget and 2018 midterm election strategy. Though Democrats were not included in the discussions, the leaders — some dressed casually in jeans, khakis and sweaters — said they were optimistic that more Democrats would be working with Republicans.

“We hope that 2018’ll be a year of more bipartisan cooperation,” Senate Majority Leader Mitch McConnell told reporters, predicting a “significant number of Democrats” would be interested in supporting Trump’s agenda.

It’s a reflection of reality: Republicans hold a razor-thin majority in the Senate and will need Democrats’ support to push through most legislation. It’s unclear, however, the extent to which Trump is willing to work with Democrats to achieve that goal.

Republicans are eager to build on the victory achieved late last year with the overhaul of the nation’s tax code.
