An internal report about alterations to a surveillance warrant the FBI got for a Trump campaign associate has raised concerns from some of Illinois' Congress members.

Federal investigators got a Foreign Intelligence Surveillance Act warrant for Carter Page, who was a policy adviser for President Donald Trump when he was running for office in 2015. The warrant was renewed several times and spanned a few months into the beginning of Trump's term.

An inspector general is expected to release findings from an investigation on Dec. 9 about the warrant application before testifying to the Senate Judiciary Committee on Dec. 11.

U.S. Sen. Dick Durbin, D-Springfield, is on that committee. Asked about reports that the review will show an FBI attorney tampered with documents, Durbin said: “I have no idea.”

“I’m sorry, I don’t know what that is,” Durbin said Friday. “I don’t know.”

The report has not yet been released, but has been widely reported in the media.

Messages seeking an updated statement were not immediately returned.

U.S. Rep. Darin LaHood, R-Peoria, said what he has heard was troubling.

“It’s very disturbing under our system that it looks as if there was an FBI agent or multiple FBI agents that lied on a FISA warrant application,” LaHood said. “As a former federal prosecutor, when you go to a federal judge and you get put under oath and you lie or you alter that application, there have to be consequences and clearly there were things left out of that FISA application.”

U.S. Rep. Rodney Davis, R-Taylorville, said he’d heard about the report.

“I’m going to wait for the entire report to come out to cast judgment,” Davis said. “But if it’s true, it’s clearly disappointing. But I want to see the report. I’m interested in seeing it. I think it’s overdue.”

“People want to know and people need to be held accountable within our government within the highest levels if there is an abuse of the constitution,” LaHood said.

The report is one review of the origins of the initial investigation into allegations that Trump colluded with Russian officials. Special Counsel John Durham also is investigating possible criminal activity surrounding the probe.
