Piers Morgan doubles down on Duchess Meghan's Oprah interview: 'I still don't' believe her

Piers Morgan stands by his comments he made Monday on ITV's "Good Morning Britain" about Duchess Meghan and Prince Harry's interview with Oprah Winfrey that led to his departure from the show Tuesday.

The ex-host took to Twitter Wednesday to defend his original statements that he didn't "believe a word" Meghan said in Sunday's two-hour long, revelatory interview about her experience with the monarchy. The two most toxic allegations she made in the interview concerned her description of the palace's cold indifference to her mental stress, and their claim that an unnamed royal family member expressed "concern" about "how dark" their son Archie's skin would be.

Sharing a picture of a Winston Churchill quote, Morgan wrote: "On Monday, I said I didn’t believe Meghan Markle in her Oprah interview. I’ve had time to reflect on this opinion, and I still don’t." 

"If you did, OK. Freedom of speech is a hill I’m happy to die on," he added. "I’m off to spend more time with my opinions."

ITV confirmed Morgan's departure from the program in a Tuesday statement to USA TODAY: "Following discussions with ITV, Piers Morgan has decided now is the time to leave 'Good Morning Britain.' ITV has accepted this decision and has nothing further to add."

Morgan's words spark complaints and an investigation

The U.K.'s Office of Communication reported receiving more than 41,000 complaints from the public regarding Morgan's comments on the interview with the Duke and Duchess of Sussex. 

"I'm sorry, I don't believe a word she says, Meghan Markle. I wouldn't believe her if she read me a weather report," Morgan said. "The fact that she's fired up this onslaught against our royal family, I think is contemptible."

The next day, Morgan stormed off the set of the program following a heated discussion with a fellow presenter about Harry and Meghan’s allegations about racism in the royal family.

"We have launched an investigation into Monday’s episode of Good Morning Britain under our harm and offence rules," the communications spokesperson told USA TODAY Tuesday. 

According to a report by Variety, a complaint was also filed directly from the Duchess to the CEO of ITV after Morgan's commentary. The report said Meghan's complaint was filed with concern that his words would "affect the affect the mental health dialogue in the U.K. and may even impact someone contemplating suicide."

USA TODAY reached out to ITV and Meghan's spokesperson and both declined to comment.

Celebrities comment on Morgan's departure 

Celebrities commented on Morgan's departure from "Good Morning Britain" on Twitter, both supporting him and telling their own stories of alleged harassment from the former host. 

"The Good Place" actress Jameela Jamil, who has feuded with Morgan in the past, spoke out about how Morgan's words affected her in the past. 

"I almost killed myself a year ago because of Piers Morgan’s relentless campaign of lies and hatred against me last February. I’m glad I’m still alive today for many reasons," she wrote. 

Last February, Morgan released screenshots of a conversation with late reality TV show host Caroline Flack and accused Jamil of "online harassment." 

Jamil also tweeted a gif of Morgan Tuesday writing: "May we NEVER have to watch minorities have to go on mainstream news and have to *defend* their right to be treated with dignity and respect... ever again."

Morgan did receive support fromhis former America's Got Talent co-judge Sharon Osbourne. 

".@piersmorgan I am with you. I stand by you," Osbourne tweeted Tuesday morning. "People forget that you’re paid for your opinion and that you’re just speaking your truth."

Buckingham Palace responds to Harry, Meghan interview 

Before ITV announced Morgan's exit Tuesday, Buckingham Palace issued a four-sentence response to the Winfrey interview, saying the couple's accusations of racism and lack of support are taken "very seriously" and will be addressed by the royal family "privately."

"The whole family is saddened to learn the full extent of how challenging the last few years have been for Harry and Meghan. The issues raised, particularly that of race, are concerning," the palace's statement read. "While some recollections may vary, they are taken very seriously and will be addressed by the family privately. Harry, Meghan and Archie will always be much loved family members."
