Donald Trump Video One of the 'Biggest Mistakes He Ever Made'—Mary Trump

Donald Trump's abortion video is one of the "biggest mistakes he ever made," his niece has said.

In a video released on Monday, Donald Trump said that abortion policy should be left to each individual state following the overturning of Roe vs. Wade in 2022. He also did not endorse a federal limit on abortion, which caused backlash from some Republicans and anti-abortion groups.

Abortion has proven to be an electorally troublesome issue for Republicans. It was widely linked to the GOP underperforming in the midterm elections in November 2022, and Donald Trump is under pressure to neutralize its impact before voters head to the polls in the presidential election.

Writing on her blog on Monday night, Mary Trump responded to the video and said it handed Democrats a major win.

She wrote: "In a video posted to Truth Social today, Donald made one of his boldest statements yet about abortion, declaring he had 'proudly ended Roe vs. Wade.' In so doing, he just handed Democrats the political ad of the season.

"Political analysts say Republicans are in trouble on abortion rights, which are set to play a key role in 2024. Democrats have recently announced plans to put abortion measures on the ballot in several states, and the Florida state Supreme Court already did them that favor."

Florida's Supreme Court ruled on April 1 that a measure to legalize abortion until viability could appear on the ballot in November. The inclusion was allowed despite a legal challenge from state Attorney General Ashley Moody.

Mary Trump, a frequent critic of her uncle, also said that the former president had managed to alienate two groups he needs to win the 2024 presidential election.

"Donald might have thought he was making his anti-abortion rhetoric more palatable by suggesting he thinks abortion should be left to the states, but he managed to p*** off the two groups he needs: first is the right, who want him to pass a national ban; and second are independents, who don't want states to ban abortion. Nice job, Donald," she wrote.

Newsweek contacted representatives for Donald Trump for comment via email outside of normal office hours.

The former president has faced fury from some Republicans over his stance on abortion following the release of the video, with GOP South Carolina Sen. Lindsey Graham saying that he "respectfully" disagreed.

He added: "I will continue to advocate that there should be a national minimum standard limiting abortion at 15 weeks because the child is capable of feeling pain, with exceptions for rape, incest and life of the mother."

Marjorie Dannenfelser, who is president of the Susan B. Anthony group—a right-wing nonprofit organization that seeks to limit abortion—also hit out.

"We are deeply disappointed in President Trump's position. Unborn children and their mothers deserve national protections and national advocacy from the brutality of the abortion industry," Dannenfelser said in a statement.

"The Dobbs decision clearly allows both states and Congress to act. Saying the issue is 'back to the states' cedes the national debate to the Democrats who are working relentlessly to enact legislation mandating abortion throughout all nine months of pregnancy. If successful, they will wipe out states' rights."

Dobbs vs. Jackson Women's Health Organization was a decision by the U.S. Supreme Court in 2022 in which it held that the Constitution of the United States does not confer a right to abortion.

In a post on Truth Social Trump hit back at Graham and Dannenfelser, saying they should focus on elections instead.

"Senator Lindsey Graham and Marjorie Dannenfelser should study the 10th Amendment and States' Rights. When they do, they should proudly get on with helping Republicans to WIN ELECTIONS, rather than making it impossible for them to do so!" he wrote.

A survey conducted for Newsweek by Redfield & Wilton Strategies in February shows that voters are split over whether abortion rights should be left up to individual states.

In total, 40 percent of voters agree with Trump that abortion rights should be left to state governments, while 40 percent said the federal government should determine abortion laws. Finally, 20 percent said they did not know which level of government should decide.

The poll was conducted on February 10 among 1,500 eligible voters in the U.S. and has a margin of error of 2.53+/-.
