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.
