Trump is trying to peel off moderate Democrats to back his border wall. So far, none are biting.

On Tuesday, Day 25 of the government shutdown, Senate Republicans said they are mostly on board with Senate Majority Leader Mitch McConnell's (R-Ky.) hands-off approach to negotiating a way out of the impasse, House Democrats said they are united behind Speaker Nancy Pelosi's position that President Trump has to sign their legislation to reopen the government before they will discuss border security, and Trump tried to peel off some rank-and-file Democrats to join his push for a border wall paid for by American taxpayers. So far, he's gotten no takers.

The White House had invited a handful of centrist Democrats to the White House for a Tuesday afternoon lunch, but all of them turned him down, citing previous engagements or lack of interest in being used as pawns. Pelosi, who wasn't invited, told her Democratic colleagues Monday night that she had no problem with other Democrats attending, USA Today reports. "They can see what we've been dealing with," Pelosi joked to House Majority Leader Steny Hoyer (D-Md.). "And they'll want to make a citizen's arrest."

After a House Democratic caucus meeting Tuesday in which Pelosi reportedly urged Democrats to stick together, Hoyer told reporters: "Is anybody surprised that the president is trying to get votes wherever he can get votes? ... We are totally united. Totally." Trump has invited more rank-and-file Democrats, part of the bipartisan "Problem Solvers" caucus, to the White House on Wednesday, and it isn't clear how many will attend, if any.

No known discussions have taken place between Democratic congressional leaders and the White House since Trump abruptly walked out on the last meeting. Bipartisan groups of senators have been huddling, looking for an off-ramp to the longest shutdown in U.S. history, "but hopes are slim in the Senate that they can reach a solution that the president will endorse," Politico notes.
