Treating the Federal Communications Commission like his own personal enforcer, President Donald Trump said on social media Sunday that NBC’s Kristen Welker would be “reported to the FCC for rebuke or punishment” over a TV segment he didn’t like.

In a separate post, Trump complained in all caps about “fake polls” and said “something must be done about it,” adding, “FCC to the rescue!”

The posts were Trump’s most explicit efforts yet to direct the FCC to carry out his wishes. FCC Chair Brendan Carr, a Trump appointee and close ally, did not respond to CNN’s request for comment on the matter.

On Sunday, Trump posted a long missive about what he described as mischaracterizations of his endorsement record in primaries.

He wrote: “Kristen Welker, the Unpopular ‘Hostess’ of the once great Meet the Press, now considered Meet the Fake Press, just stated that Donald Trump has ‘mixed results’ on his Endorsements of Candidates, when the recent WINS of Darline Graham and Mike Mazzei, stand at 100% for the U.S. Senate, and 98% for the U.S. House, recently and over the longterm. How can anyone be allowed to say this, working for freely given Public Airwaves?”
