(CNN) Republican Sen. Susan Collins of Maine, who voted to acquit President Donald Trump at his impeachment trial, said Wednesday that her acquittal vote was "not based on predicting (Trump's) future behavior," following previous comments she made saying Trump had "learned from this case."

When asked by CNN on Wednesday what Trump had learned from the impeachment process, Collins would not directly answer the question, instead defending her position and saying that her vote was "solely" based on whether the House managers reached the high bar for removing a sitting president, she said.

"My vote to acquit the President was not based on predicting his future behavior. It was based solely on the issue, whether or not the house managers reached the high bar for removing a duly elected president," Collins said. "And in my judgment, they did not."

"That was the basis for my vote," she said, accusing the media of misrepresenting her position without specifying what she meant by that criticism.

Collins continued, "So I don't understand why you keep linking how I voted to whether or not the President's learned to be more careful, in conversations with foreign leaders, which is what I was talking about."
