Rand Paul pledges to force Hunter Biden vote if GOP backs Dem impeachment witnesses

Sen. Rand PaulRandal (Rand) Howard PaulRand Paul volunteering at hospital after negative coronavirus test Georgia governor says he didn't know asymptomatic people could spread coronavirus McConnell: Impeachment distracted government from coronavirus threat MORE (R-Ky.) sent a public warning shot on Monday night, saying that if Republicans support Democrats' impeachment witness requests, then he will force votes during the trial on calling witnesses conservatives want to hear from. 
 
"My colleagues can’t have it both ways. Calling for some, while blocking others," Paul tweeted, referencing a Politico report on a similar private warning he gave his GOP colleagues against supporting Senate Minority Leader Charles SchumerCharles (Chuck) Ellis SchumerHealth care workers account for 20 percent of Iowa coronavirus cases Pressure mounts on Congress for quick action with next coronavirus bill Schumer names coronavirus czar candidates in plea to White House MORE's (D-N.Y.) request that former national security adviser John BoltonJohn BoltonChina sees chance to expand global influence amid pandemic Trump ignores science at our peril Bolton defends decision to shutter NSC pandemic office MORE testify. 
 
"If we are going to give a platform to witnesses the Dems demand, I look forward to forcing votes to call Hunter Biden and many more!" Paul continued.

Susan CollinsSusan Margaret CollinsPresident tightens grip on federal watchdogs The Hill's 12:30 Report: Trump gets new press secretary in latest shake-up Trump takes heat for firing intel watchdog during pandemic MORE (R-Maine) said last week that she was working with a small group of Republican senators to ensure the resolution allows for both Trump's team and House impeachment managers to call witnesses. 
 
Collins has not said if she would support calling witnesses, agreeing, along with the rest of the Senate GOP conference, to delay that decision until after opening arguments and questions from senators. 
 
 
"I support the Clinton model, which means that we will have opening arguments first. Then we'll have a vote on witnesses, and at that stage I presume I'll be voting in favor of hearing from John Bolton, perhaps among others. That could change," Romney told reporters on Monday. 
 
Democrats would need to peel off four Republican senators to successfully call a witness or compel the administration to hand over Ukraine-related documents.

McConnell told Fox News Radio that opening the door to witnesses would pave the way for a "kind of mutual assured destruction," adding that Republicans would "want the whistleblower. We're going to want Hunter Biden."

"You can see here that this would be a kind of mutual assured destruction episode that would go on for a long time," McConnell said.
