Senator Charles Schumer says he'll recuse himself from any hearings Congress will have about the Comcast/Time Warner Cable merger.
Schumer is a member of the Senate Judiciary Committee's antitrust subcommittee.
Federal regulators and lawmakers will scrutinize how the combination will affect competition and consumers.
Schumer says he didn't know that his brother, Robert Schumer, was one of the main lawyers representing Time Warner Cable in the deal.
"I did not discuss this issue at all, the merger at all, with my brother," Schumer said. "When I learned from the American lawyer that he was a lead lawyer on the case, I decided to recuse myself. That's the right thing to do."
When the $45 billion deal was announced last Thursday, Schumer's office issued a statement saying he believed that the merger would keep current jobs and create new ones.
Time Warner Cable is the parent company of NY1.
