With only a day to go before the Senate impeachment trial begins, no one knows which witnesses will be allowed to testify, or if any witnesses will be allowed at all. There is no legitimate reason for McConnell to block new witness testimony, and all available evidence should be carefully considered.

Americans agree. According to a new poll, 69% believe the Senate trial should feature testimony from new witnesses.

CNN POLL: “Nearly seven in 10 (69%) say that upcoming trial should feature testimony from new witnesses who did not testify in the House impeachment inquiry.”

A majority of Americans also believe that Trump abused his power and obstructed Congress.

CNN POLL: “The new poll also finds majorities of Americans view each of the charges on which Trump will face trial as true: 58% say Trump abused the power of the presidency to obtain an improper personal political benefit and 57% say it is true that he obstructed the House of Representatives in its impeachment inquiry.”
