Senate Homeland Security and Governmental Affairs Committee Chairman Ron Johnson Ronald (Ron) Harold JohnsonSecond GOP senator to quarantine after exposure to coronavirus GOP-led panel to hear from former official who said Burisma was not a factor in US policy The Hill's Morning Report - Sponsored by The Air Line Pilots Association - Trump contradicts CDC director on vaccine, masks MORE (R-Wis.) canceled a vote scheduled for Wednesday afternoon on a subpoena stemming from his months-long probe into Hunter Biden and Burisma Holdings.

“Out of an abundance of caution, and to allow time for you to receive additional briefings, I will postpone a vote to subpoena records and an appearance from former Blue Star Strategies consultant Andrii Telizhenko about his work for the lobbying firm,” Johnson said in a note to committee members, a copy of which was obtained by The Hill.

Johnson told reporters that he was pulling the vote because of "some discrepancies brought up in what we had been told."

"There were issues raised," Johnson said. "There were discrepancies in what had been told in one briefing versus the next briefing, and then even greater discrepancies in staff notes."

The committee had been poised to vote Wednesday afternoon to subpoena Telizhenko for documents and an interview. Johnson characterized him as willing to participate with the committee's investigation but currently he is barred by a nondisclosure agreement.

Instead of subpoenaing Telizhenko, Johnson indicated that he would instead target Blue Star Strategies, which has ties to Burisma.

“While we work through those questions, at the suggestion of both Republican and Democrat Committee members, we will instead go straight to the source and compel the same records and an appearance directly from Blue Star Strategies,” Johnson added in the message to committee members.

Johnson told reporters Wednesday that he would subpoena Blue Star Strategies, a decision he hoped could win over Peters's support. If Johnson has to force a committee vote, which would be sparked if Peters objects, the GOP senator indicated that was unlikely to happen this week.

"You do need to provide proper notice," Johnson said. "I wouldn't want to give them [Blue Star] any excuse to say 'we didn't get proper notice.' "
