Kinzinger called the former president a “snowflake” and “one of the weakest people I’ve ever seen” in an interview Monday with CNN’s Anderson Cooper.
The comment came in the middle of a discussion about Trump’s vitriolic response replaced George W. Bush’s speech on the 20th anniversary of the September 11 terrorist attacks.
Bush said Saturday that there is “little cultural overlap between violent extremists abroad and violent extremists at home.” Trump returned on Monday, saying Bush “shouldn’t be lecturing anyone” because of his role in “taking us to the sands of the Middle East.”
Kinzinger, a frequent critic of the twice-impeachable Trump, suggested a response that showed impotence.
“I mean, If you think about it, what is strength? Strength is not someone who wakes up whenever they feel they have such a lack of self -esteem, they feel like they should attack,” Kinzinger said.
“A person with strength is someone who can take criticism, who can come out on a day like September 11 and bring people together,” he continued. “People on my side like to use the term snowflake when talking about people who are really hurt. So, that’s Donald Trump.”
“I look at who he is as a person and the amount of offended he gets with anything and how he comes out and punches,” Kinzinger added. “He was going to attack a radio host, for goodness sake, when he was president of the United States.”
