Just before the vote was about to begin, Rep. Max Miller of Ohio, one of Santos’ Republican colleagues, sent an email to the full Republican conference, writing that he and his mother were victims of credit card fraud tied to Santos’ campaign and that he would be voting to remove Santos.

“Neither my Mother nor I approved these charges or were aware of them,” Miller wrote in the email obtained by NPR. “We have spent tens of thousands of dollars in legal fees in the resulting follow up.”

It’s literally because it was starting to affect them personally.
