Piers Morgan, the former "America's Got Talent" host and the former editor of the The Daily Mirror British tabloid, slammed Duchess Meghan Markle and Prince Harry on Twitter for appearing in a video urging Americans to vote in the Nov. 3 election.

Morgan deemed their remarks "unacceptable" and argued their comments attempted to sway voters away from Trump. He also urged Queen Elizabeth II to remove the couple's royal titles.

"He’s still a royal. They both are. ... If they drop the titles, they can say what they like. But the titles bring in their $$$$$$," Morgan tweeted.

Members of the royal family are supposed to be politically neutral. While both Meghan and Harry urged Americans to vote, neither explicitly named or endorsed a specific candidate. Many, however, interpreted their comments as critical of Trump even though Harry pointed out in the video he never has been able to vote.

"As we approach this November, it's vital that we reject hate speech, misinformation, and online negativity," Harry said in the video. "This election, I'm not going to be able to vote here in the U.S. But many of you may not know that I haven't been able to vote in the U.K. my entire life."

Buckingham Palace appeared to distance itself from the couple's comments, telling British tabloids the couple were no longer working royals and that Harry was speaking in a personal capacity.

Harry and Meghan bowed out of their royal duties in January, announcing they would step down as senior members of the royal family, with plans to split their time between North America and Britain.

President Trump also was critical of Meghan and said he is not a fan of the former actress.

"I'm not a fan of hers and I would say this, and she probably has heard that, but I wish a lot of luck to Harry — he's going to need it," Trump said at a White House news briefing.

In the "2020 Time 100" video, Harry and Meghan spoke about the importance of voting and deemed the upcoming election the most important of our lives.

"Every four years we are told the same thing: that this is the most important election of our lifetime," Meghan said. "But this one is. When we vote, our values are put into action and our voices are heard. Your voice is a reminder that you matter because you do and you deserve to be heard."
