Washington (CNN) Nan Whaley, the mayor of tragedy-stricken Dayton, Ohio, expressed shock on Thursday morning after President Donald Trump lashed out against her and Ohio Sen. Sherrod Brown on Wednesday in response to a press conference they held following his Dayton hospital visit.

"He was well received by victims and first responders," Whaley told CNN's John Berman in an interview on "New Day," echoing her previous comments after reading Trump's tweets. "I'm at a loss for why all this vitriol came immediately after he had a good visit at the hospital."

Trump tweeted Wednesday that after receiving "tremendous enthusiasm & even Love," Trump wrote, he "saw failed Presidential Candidate (0%) Sherrod Brown & Mayor Whaley totally misrepresenting what took place inside of the hospital."

"Their news conference after I left for El Paso was a fraud. It bore no resemblance to what took place with those incredible people that I was so lucky to meet and spend time with. They were all amazing!" he said.

At their press conference, Brown and Whaley expressed primarily positive sentiments regarding the President's hospital visit, though they did criticize his past rhetoric.
