Attorney General Jeff Sessions Jefferson (Jeff) Beauregard SessionsTrump's policies on refugees are as simple as ABCs Ocasio-Cortez, Velázquez call for convention to decide Puerto Rico status White House officials voted by show of hands on 2018 family separations: report MORE on Tuesday refused to say whether he has discussed the pending AT&T-Time Warner merger with anyone at the White House.

The White House and Makan Delrahim, the Justice Department's antitrust chief, have both denied that there has been any interference in the merger negotiations.

Cicilline, visibly angered by the response, unsuccessfully tried to get the chairman to compel Sessions to be more forthcoming.

"Either you’re invoking the Fifth Amendment or you’re invoking executive privilege," Cicilline said. "You just can’t decline to answer because it’s uncomfortable."

According to multiple news reports that emerged last week, the Justice Department's antitrust division had demanded that AT&T and Time Warner sell off CNN in order to get their merger approved. CNN is a Time Warner subsidiary.

Earlier in Tuesday's hearing, Sessions declined to comment on the merger discussions but threw doubt on the reports.

"I would just tell you that I would not be able to accept as accurate news reports that have come out on that," he said.

Critics have raised the possibility that demands to sell CNN may have been part of President Trump's personal vendetta against the network. And Trump ally Rupert Murdoch has reportedly offered to buy CNN.
