House Democrats are making a serious mistake by rushing to a vote on impeaching President Trump rather than attempting to compel important witnesses to testify who could shed more light on what happened with Ukraine.

The public impeachment hearings have wrapped up, and Democrats are confident that they have enough to draft impeachment articles that can pass the House of Representatives. Taken together, witnesses have painted a portrait of Trump and his personal lawyer Rudy Giuliani being myopically obsessed with getting Ukraine to publicly commit to investigations related to the 2016 election and Joe and Hunter Biden. And that obsession led to an attempt to leverage U.S. foreign policy to achieve this purpose.
