Piers Morgan accuses Gayle King of being Harry and Meghan's 'PR mouthpiece' in Twitter rant

• Morgan tweeted King after she spoke about conversations she had with Prince Harry.
• King said that Prince Harry told her his recent conversations with his father were "not productive."

Piers Morgan lashed out at TV host Gayle King in a Twitter rant in which he called King a "PR mouthpiece" for Prince Harry and Meghan Markle.

Morgan's reaction comes after King, on her show "CBS This Morning," talked about Prince Harry and Markle's latest issues following their interview with Oprah Winfrey.

Morgan tweeted King directly, and wrote: "Hi @GayleKing - rather than acting as your Sussex friends' PR mouthpiece to facilitate their ongoing public trashing of our Royal Family, how about doing your job as a journalist and ask them about all the lies they told in @Oprah's interview?"

He added: "America should hear THE truth."

King is friends with Markle, and the 66-year-old morning show host attended Markle's baby shower. On Tuesday, while hosting "CBS This Morning," King spoke about a recent conversation she had had with Prince Harry and Markle.

King told viewers that Prince Harry told her that the first conversations he had with his brother Prince William and his father Prince Charles after the Oprah interview were "not productive."

"The word I was given was that those conversations were not productive. But they are glad that they have at least started a conversation," King said.

She also said that no one in the royal family has talked to Markle yet following the bombshell interview in which Markle said she had suicidal thoughts after joining the royal family. Markle and Prince Harry also said that a member of the royal family had had "concerns and conversations" regarding the color of Archie's skin.

Morgan continues to insist he does not believe what Markle said in her interview with Oprah. His assertion that Markle was lying led to an on-air clash with his "Good Morning Britain" co-host Alex Beresford. This, in turn, led to Morgan storming off of the set and, later that day, quitting the show altogether.
