"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 SchumerChuck SchumerBiden confident Republicans will vote to raise debt ceiling Hochul touts readiness, distance from Cuomo Senate confirms Biden's first ambassador MORE's (D-N.Y.) request that former national security adviser John BoltonJohn BoltonWant to evaluate Donald Trump's judgment? Listen to Donald Trump Will Pence primary Trump — and win? Bolton: Trump lacked enough 'advance thinking' for a coup 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.

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.

Bolton was one of four witnesses requested by Democrats and said he would testify if subpoenaed. 
 
"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.
