Horowitz, in his report, concluded that the FBI's decision to open an investigation was not motivated by political bias. He also concluded that the FBI had “an authorized purpose” to launch a probe to “obtain information about, or to protect against, a national security threat or federal crime, even though the investigation also had the potential to impact constitutionally protected activity.”

The inspector general outlined seven “significant inaccuracies and omissions” in the FBI's application to the Foreign Intelligence Surveillance Court to monitor Page, some of them related to the information received from Christopher Steele, an ex-British intelligence agent who authored the Trump-Russia dossier.

“We found that members of the Crossfire Hurricane team failed to meet the basic obligation to ensure that the Carter Page FISA applications were ‘scrupulously accurate,’ ” the report states.

Graham pointed to Horowitz's finding that interviews with a "primary sub-source" of the dossier "raised significant questions about the reliability of the Steele election reporting."

"What they did from that point on, this whole endeavor became a criminal conspiracy to defraud the court, to trample on the rights of an American citizen, Mr. Carter Page," Graham said.



He added that "if that doesn't bother you, you hate Trump way too much."

Horowitz is scheduled to testify about his findings before Graham's committee this week.

"On Wednesday, we're going to have a hearing, and we're going to get the good, the bad and the ugly," Graham said.

GOP senators on the panel signaled Monday that they have significant concerns about Horowitz's findings.
