US President Donald Trump on Sunday said in a post on Truth Social that NBC's Kristen Welker will be reported to the FCC for "rebuke or punishment", after he said she reported the Republican President had mixed results in his endorsement of candidates.

The president took issue with Welker’s characterization of his record for endorsing candidates during the primary elections as having “mixed results.”

The President is unhappy with suggestions by the host of "Meet The Press" that his endorsements are becoming less effective as his poll numbers slump.
