Deputy FBI Director Andrew McCabe has rescheduled his testimony in front of the House Intelligence Committee until next week, Fox News is reporting.

McCabe was reportedly scheduled to testify behind closed doors on Tuesday. Justice Department officials blamed a "scheduling error" for the postponement, the news network reported.

But sources told Fox News that members of the committee are suspicious of the reason given for the delay. And one source believes the scheduling conflict was sparked by a Fox News report on Justice Department official Bruce Ohr.

Fox News reported Ohr, who was demoted for concealing his meetings with those behind the anti-Donald Trump "dossier," had even closer ties to Fusion GPS — the company responsible for the controversial document. It said Ohr's wife, Nellie, had worked for Fusion GPS during the presidential election.

"McCabe has an Ohr problem," one congressional source told the news network.

Fox News noted there was speculation Justice Department officials believed McCabe was not prepared to respond to questions about Ohr.

McCabe also was expected to be questioned about Peter Strzok, the FBI agent reassigned from special counsel Robert Mueller's probe over allegedly anti-Donald Trump text messages sent during the presidential campaign.

According to The Hill, President Trump and others have used the allegations about Strzok to push the argument that special counsel Robert Mueller's probe is politically motivated.
