Former Vice President Joe Biden said Friday that he would not comply with a subpoena to testify in the Senate impeachment trial against President Trump, should one be issued to him.

Any testimony from the 2020 Democratic contender for the White House before the Senate would draw attention away from Trump's alleged wrongdoing and would effectively let the president off the hook, Biden claimed in an interview with the editorial board of the De Moines Register in Iowa.

"What are you going to cover?" Biden said to Register Executive Editor Carol Hunter in response to a question about the possibility of his participation in the trial. "You guys are going to cover for three weeks anything that I said. And (Trump's) going to get away."
