President Donald Trump said he has "confidence" in James Comey, but criticized the FBI director for "saving Hillary Clinton's life" by not recommending charges over her use of a private email server as secretary of state.

In an interview on Fox Business Network, Maria Bartiromo asked Trump about so many Obama administration holdovers still serving in the government.

"Was it a mistake not to ask James Comey to step down?" she asked.

Trump said "it's not too late" to do that, but said he has "confidence" in Comey, who is investigating Russia's interference in the 2016 election and possible coordination between Russia and members of Trump's campaign.

"Remember: he saved Hillary Clinton. He saved her life," said Trump, adding that Comey outlined Clinton's guilt last July but then decided not to recommend charges be pursued.

Bartiromo then pressed Trump on why Comey is still on the job if he feels that way.

Trump answered that Clinton would be going to "trial" right now if it weren't for Comey's decision.

The conversation then moved to former Obama national security adviser Susan Rice and her handling of raw intelligence.

Fox News reported last week that Rice requested to unmask the names of Trump transition officials caught up in incidental surveillance.

Bartiromo asked Trump about the Obama administration relaxing the rules about sharing intercepted personal communications and the ability to share those with 16 other intelligence agencies.

Trump said it's "so obvious" what the Obama administration was doing, saying "nobody believes" Rice's actions were not political.

He said "so many people" have since apologized to him and told him that he was right to accuse President Obama of ordering "wiretapping" of Trump Tower.

"What they did is horrible," the president concluded.
