“I think that would be helpful. President Clinton did that in 1999. It took him a while, but, finally, he did apologize for his actions,” Collins said during an interview with CBS’s Norah O’Donnell when asked if Trump should apologize.

Collins said during the interview that it was “improper” for Trump to bring up former Vice President Joe Biden and his son Hunter Biden during the July phone call and that Trump’s conversation with Ukrainian President Volodymyr Zelensky was “far from … perfect.”

Collins announced on Tuesday that she would vote to acquit Trump on the two House-passed impeachment articles: abuse of power and obstruction of Congress.
