Texas Rep. Louie Gohmert, a Republican backed by the Tea Party movement, suggested that the president was misled by Senate Majority Leader Mitch McConnell of Kentucky, whom the crowd repeatedly booed. Jan Morgan, a spokeswoman for the Citizens for Trump grass-roots group, said “the president was ill-advised when he made his decision.” And former Alaska governor Sarah Palin accused the swamp — which is what Trump likes to call the Washington establishment — of trying to overpower the president.

“The forgotten man and woman in this country, they stood up, and we beat the swamp. But, alas, 10 months later, guys, the swamp, it’s trying to hijack this presidency,” said Palin, who unsuccessfully ran for vice president in 2008 and was one of the leaders of the Tea Party movement that predated the Trump movement. “The swamp is trying to steal the victory that we worked so long and hard for — to steal the victory that a lot of us put our reputations on the line for. We voted to put America first, not the political elite that had ignored us for decades.”
