The hearing had previously been scheduled for April 2. The committee gave no reason for the delay.

Comcast, the No. 1 U.S. cable operator, has announced plans to buy rival Time Warner Cable for $45.2 billion.

The deal has raised eyebrows, although Comcast has pledged to divest 3 million subscribers, so the combined customer base of 30 million would represent just under 30 percent of the U.S. pay television video market. A combined Comcast and Time Warner Cable would also have roughly one-third of the high-speed Internet market.

The proposed transaction is subject to approval by the U.S. Federal Communications Commission and the U.S. Justice Department.
