At least one Republican official expressed disbelief at President Donald Trump's closing message delivered Monday, on the eve of Election Day, according to an account from an NBC News correspondent.

MS NOW's Jonathan Lemire joined "Morning Joe," the network's long-running morning program, Tuesday morning to discuss why members of the president's own party have grown so frustrated with him. During the segment, co-host Joe Scarborough catalogued what he described as a string of missteps by Trump.

"Tariffs, Minneapolis, the Iran war, Epstein, you just go on and on. Data centers, AI, the Kennedy Center, putting his name on that, all of the vanity projects, all of the, you know, the enrichment, the corruption," Scarborough said.

Chief White House correspondent Peter Alexander said he had been speaking with Republicans on Monday as Trump delivered his remarks in front of the Reflecting Pool on the National Mall in Washington.

"One Republican texted me and said, 'This is not real life,'" Alexander recalled.

"It just feels like they're [Republicans] begging for a little bit of help," he said. "[Trump] has saddled them with all these things you indicate. And you can't fathom — you can't even make up this stuff. The idea that he's going to walk over the Reflecting Pool and talk about the algae on the closing day for half of his closing message speech and beyond right now."

Alexander said Republican concern was closely tied to the size of the numbers on election day, arguing that Donald Trump's power is a function of how close Republicans keep the results on the Senate side in particular. "The question is, if they get beat badly," he said. The Senate margin carries weight because majority control determines the chamber's agenda, its committee chairmanships, and the fate of presidential nominees awaiting confirmation.

He also raised the question of which Republicans might be willing to step forward and publicly break with Trump as the party looks toward the 2028 presidential election.

"Democrats are going to do that in the next couple of weeks, or you probably know how soon these conversations happen or the announcements come," Alexander continued. "But the Republicans, if Donald Trump gets shellacked, then all of a sudden we'll see how soon they come out. What does it say about JD Vance? How does he change his sort of messaging going forward?"

Alexander added that the bigger discussion for Democrats would be their "Day One" message on Jan. 3, when the next Congress is sworn in and a new House majority would take control of committee chairmanships and the investigative authority that comes with them. He predicted that television networks would chase shiny objects, while others would be prepared to begin investigations, hearings, impeachments and more.
