Van Hollen told Jon Karl on ABC’s “This Week” that Senate Democrats are pushing for a “fair trial” where they are permitted to call witnesses and obtain necessary documents. 

"Is Sen. Mitch McConnell, the Republican leader, going to try to rig this trial, working in lockstep with the president and his lawyers? Or is he going to allow a fair trial?" Van Hollen asked.

"We keep hearing President Trump say he's going to be exonerated," he added. "Look, if you have a rigged trial there's no exoneration in acquittal."

Van Hollen said it was “too early” to tell how many Republicans will support more witnesses and documents in the trial but added that those who vote against it will be “complicit in a cover-up.”
