Asked separately if she thought Hunter Biden had relevant information for the impeachment trial, Collins replied: "How can I tell? You're asking me to pre-judge the evidence."

Two crucial swing-vote senators declined on Wednesday to say if they think Hunter Biden should testify during the soon-to-begin impeachment trial.Sens.(R-Maine) and(R-Alaska) both told reporters that it’s too soon to make a decision on Biden, the son of former Vice President, arguing the witness fight should wait until after opening arguments and questions from senators."There will be this time in the process where we will have an opportunity to make a determination as to what further information we need. Whether it is for Hunter Biden or Ambassador Bolton," Murkowski said. "Until that point in time I'm not thinking about each individual witness and who I'm putting in a bucket.""It’s clearly not the right time for us to judge which specific witnesses should be called," she said.
