The US Justice Department has opted not to pursue an investigation into Comcast's long-closed acquisition of NBCUniversal, a merger that President Trump has criticized as anti-competitive, according to the New York Post.

The U.S. Department of Justice has not announced that it is calling off such an investigation, but the New York Post reported Thursday that federal prosecutors have not filed a "civil investigative demand for company records" that would have moved such a probe forward, and "have no plans to do so."

"Nothing is happening," a source close to Comcast told the paper. "I think if the DoJ were going to take action, it would have happened by now."

Comcast Corp. (Nasdaq: CMCSA, CMCSK) and the American Cable Association (ACA) have been asked for comment on the report.

The report arrives almost two months after the American Cable Association, a group that represents a wide range of independent cable operators and competitive overbuilders, asked the DoJ to open up an antitrust investigation into the Comcast-NBCU deal. The ACA is concerned that the combination harms its constituents because it gives Comcast too much control of cable systems, TV stations and regional sports networks concentrated in some of the largest US local markets.
