Republican Sen. John Kennedy, a frequent defender of President Donald Trump, said on Sunday there were no real rules for how the U.S. Senate should run its impeachment trial and that the chamber could choose to hear witnesses and evidence.
"When it comes to impeachment, the rule is that there are virtually no substantive rules," Kennedy told CNN's "State of the Union." As a result, he said, there were plenty of steps the Senate could take, including forming a committee to hear evidence in the case.
The Democratic-led House of Representatives impeached Republican Trump this month for abuse of power and obstruction of Congress charges stemming from his effort to get Ukraine to investigate political rival Joe Biden, a former vice president and leading contender in the 2020 Democratic presidential race.
