Disney announced Thursday that it had reached a deal with Fox to acquire a majority of its assets for $54.2 billion including its regional sports networks and movie studios. The deal does not include Fox News or Fox Business network.

“I’m concerned about the impact of this transaction on American consumers,” Klobuchar said in a statement.

“As the ranking member of the Senate Judiciary Subcommittee on Antitrust, I have asked Senator [Mike] Lee [R-Utah], who has worked closely with me in this area in the past, and [Judiciary Committee] Chairman [Chuck] Grassley [R-Iowa] to schedule a hearing on the proposed merger,” she said.

No hearing has been scheduled yet, but a Lee spokesman told Reuters that "a hearing has not been ruled out."

Klobuchar said the acquisition would be “another industry-changing merger, which would have major implications in television, film, and media."

The Justice Department is expected to review the merger and may alter sales conditions, but some antitrust experts have predicted the deal will likely pass.
