Three Democratic senators are undecided if they should vote to convict or acquit President Donald Trump of the two charges brought against him by the House: abuse of power and obstruction of Congress.

Sens. Joe Manchin (D-West Virginia), Kyrsten Sinema (D-Arizona) and Doug Jones (D-Alabama) are all on the fence.

Manchin said Tuesday he will be undecided until the trial ends.

“I know it’s hard to believe that. But I really am [undecided]. But I have not made a final decision. Every day, I hear something, I think ‘this is compelling, that’s compelling,’” Manchin said. “Everyone’s struggling a little bit.”

Jones, a Democrat in a traditionally Republican state, said he hears both from constituents in both parties, but more from Trump supporters. He said he has begun to make up his mind, but could be swayed by new testimony.

“I don’t think I’ve totally decided. I certainly have [been] leaning one way or the other. That needle moves” Jones said. “I am leaning in certain ways but I want to hear, I truly, honestly, want to hear the entire trial.”

Sinema has made no comments since the trial began, so it is harder to tell where she stands. However, she has broken with the Democratic party in the past, including by supporting the Attorney General William Barr‘s confirmation last year.

A spokesman said she supports including new evidence so she can “make a more fully informed decision at the end of the trial.”

A few other Democrats have indicated they are undecided as well.

Sen. Gary Peters (D-Michigan) said he is undecided, and Sen. Jon Tester (D-Montana) said he’s “absolutely open to being swayed.”

Republican Sen. Rand Paul (R-Kentucky) is pretty certain a few Democrats will vote to acquit.

“I think there will be a couple who may vote not to convict Trump,” said Paul. “I’m guessing there’s an 80 percent chance that two Democrats will not vote to convict.”
