House Speaker Kevin McCarthy said on Monday that he had no idea Rep. George Santos had embellished his resume when he ran for office.

The speaker told reporters he did have some reservations about Santos's background.

"I never knew all about his resume or not, but I always had a few questions about it," he said.

McCarthy also says he was unaware a Santos staffer pretended to be McCarthy's chief of staff to court money from donors for Santos's campaign.

McCarthy says he is sticking by Santos for now and will not ask him to resign. But the speaker cautioned that Santos has a long way to go to earn people's trust.
