Donald Trump called out Hillary Clinton's claim to the FBI that former Secretary of State Colin Powell advised her to use a personal email account during her time at the State Department.

Appearing on "Fox and Friends," Trump said Clinton "lied" about Powell's advice, which he says came a full year after she started using her private server in Chappaqua, N.Y., adding that the entire situation is a "scam."

"She's a liar. I mean, she lies. She lied about the email," Trump said before turning to Powell. "She lied about Colin Powell. I saw that. He was not happy."

"The whole thing is a scam with them," Trump added. "Everything is a scam, like grifters."

Powell reacted to the news over the weekend when asked by People Magazine.

"Her people have been trying to pin it on me," Powell said.

"Why do you think?" he said when asked why Clinton's blaming him. "It doesn't bother me. But it's OK; I'm free."

According to a new biography about former President Bill Clinton, Powell reportedly suggested to Clinton that using a personal email account to send non-classified information was a good idea and made things work easier, but says now that he doesn't remember the conversation. Powell's office later told NBC that he sent a memo to Clinton about email use.

"He did write former Secretary Clinton an email memo describing his use of his personal AOL email account for unclassified messages and how it vastly improved communications within the State Department," a spokesman said.
