Claiming that FBI investigations into Hillary Clinton's emails and the Carter Page FISA warrant were "corrupt to the core," U.S. Sen. Lindsey Graham on Wednesday called for the appointment of a special prosecutor to handle both probes.

Graham, a South Carolina Republican, said FBI investigators were “in the tank” for Clinton and the FISA warrant process was abused -- possibly in a criminal fashion.

“What do you think Democrats would be saying if a Republican — if the RNC [Republican National Committee] -- hired a former British agent to go to Russia to get dirt on [Hillary] Clinton?” Graham asked Fox News' Laura Ingraham, host of “The Ingraham Angle.”

Graham said he's grown tired of talking about the Clinton email investigation and the 2016 FISA warrant to wiretap Page, the former Trump campaign adviser. He said an outside investigator could hopefully approach the issue with a nonpartisan perspective.

TRUMP REVOKES EX-CIA DIRECTOR'S SECURITY CLEARANCE

Democrats have said the FISA warrant application shows the Justice Department acted correctly in its probe. Democrats also point to ex-FBI Director James Comey's decision to announce the reopening of the Clnton email probe just days before the 2016 presidential election as an example of no bias.

Comey has since said that he was operating at the time in a world "where Hillary Clinton was going to beat Donald Trump."

Graham's remarks came a day after former FBI agent Peter Strzok was fired over text messages that were critical of Trump.

Strzok vigorously defended himself at a combative House hearing in July, speaking publicly for the first time since the texts were revealed. He insisted that the texts — including ones in which he called Trump a “disaster” and said “We’ll stop” a Trump candidacy — did not reflect political bias and had not affected his investigations.

Strzok was also a lead investigator on the probe into Democrat Clinton’s email server in 2016.

Trump has repeatedly taken aim at Strzok on Twitter, saying his critical text messages showed that Mueller’s investigation is a hoax.
