As Verizon’s $3.6 billion proposal to purchase spectrum from various cable companies continues to be examined by both the FCC and the Justice Department, The Hill‘s Andrew Feinberg reports Sen. Heb Kohl, head of the antitrust subcommittee of the Senate Banking Committee, wants the deal to be run through with a fine-toothed comb:

In a letter addressed to FCC Chairman Julius Genachowski and Attorney General Eric Holder, Kohl makes clear that he’s not prejudging the deals to be unlawful under the Communications Act or antitrust laws. But he also makes clear that he believes the transactions should be “examined closely” because they present “serious competition concerns.”
