Hillary Clinton created her own problems by using a private email server, Fox News anchor Chris Wallace agreed Monday, but he hates to hear Republicans and GOP nominee Donald Trump threatening to keep investigating her even after the election is over, and he thinks FBI Director James Comey "should have shut his mouth."

"I hate this," he said on the "Outnumbered" program, admitting his comment could get him thrown off the show's couch. "We have had an awful lot of this [and] it is a legitimate issue."

However, the idea that Republicans, including House Oversight Committee Chairman Jason Chaffetz, R-Utah, are threatening Clinton with further investigations and even impeachment, should she win the presidency, bothers Wallace.

"You have Republicans like John McCain and Richard Burr and Ted Cruz saying we're not going to confirm any of her nominees for the Supreme Court, just going to block it for four years," Wallace said. "There are other things to do. America has other problems."

And whether Clinton is elected president or not, it's time to "get on with life," Wallace continued.

"It is not like the email issue hasn't been litigated and the Clinton Foundation," he said. "We're going back to Whitewater in the 1990s, which went nowhere. Let's address people's problems, the things that affect their daily lives."

Wallace said, though, that even with Comey's announcement the door will not be closed on the investigation either over the next 24 hours or even for some time to come.

"I have to say I've changed on the whole Comey thing," said Wallace. "I thought when he made his announcement in July that, you can argue whether it was right or wrong, but he was not going to press for a criminal indictment, but in effect, his speech would be a legal indictment. That seemed to be to me a fairly accurate answer."

But looking back, Wallace said. "I think he should have shut his mouth."

"They should have put out an announcement [saying] the investigation is closed," said Wallace. "He shouldn't have testified before Congress. If he hadn't testified before Congress he wouldn't have felt the obligation to make the announcement then days ago.

"I think criminal prosecutors should be not seen and not heard and he became too much of a political player in this whole thing. That isn't what the FBI director is supposed to be."

Trump on Sunday was furious after hearing the news that Comey had announced that his decision against prosecuting Clinton still stood, following the examination of 650,000 emails.

"The rank-and-file special agents at the FBI won't let her get away with these terrible crimes, including the deletion of 33,000 emails after receiving a congressional subpoena," Trump said at a Sunday rally.

"Right now, she is being protected by a rigged system. You can't review 650,000 emails in eight days. "
