Mary Trump Fears There Will Not Be Enough Power to Rein In Donald Trump

Mary Trump, the niece of President Donald Trump and one of his longest-standing critics, said she fears there will not be sufficient power to rein him in after the November 3 midterm elections, though Democratic majorities could start holding him accountable. She urged America's allies to stop accommodating him.

She made the remarks in an interview with British broadcaster Andrew Marr, which aired on The Mary Trump Podcast. Marr asked about her "worst fear" if the president "loses badly in the midterms."

"There won't be sufficient power to rein him in," she said. "That's why I think it's extremely important, especially if the Democrats win in the midterms and get majorities and can start holding him accountable and slowing down the process of his degradation of America and our alliances, but also other countries need to start reining him in and hopefully what's happening in Ukraine is a wake up call."

Mary Trump on the Midterms and Republican Losses

Marr's opening question was about the president using American technology against his critics abroad. Mary Trump said the problem was "Donald being willing to impose his will on behalf of malign actors like Vladimir Putin."

She hedged her forecast for the election. "The midterm elections in America in less than three weeks now look to be a massive defeat for Republicans. I don't want to say for sure that that's what's going to happen, but that's what it looks like," she said. She added that a loss "will expose him to accountability and investigations in the way he has not been, because the Republicans have been in charge of everything."

Mary Trump is a psychologist. In her opinion, he is going through "a perfect storm of his deterioration, cognitively, emotionally and psychologically," which, combined with "his desperation," "makes for a very volatile mix."

What the Polls Show

The House numbers support her forecast more than the Senate numbers do. Democrats lead the generic congressional ballot 48.8 percent to 40.3 percent in PolitiKool's polling average, and the president's approval stands at 37.5 percent in PolitiKool's polling average.

The Senate is less certain. Control of the chamber is a toss-up with eight races rated toss-ups, according to PolitiKool's polling average.

What a Democratic House Could Do

A House majority would give Democrats subpoena power, control of oversight hearings and the ability to impeach.

Those powers have limits. Conviction in a Senate impeachment trial requires two-thirds of senators present. Criminal contempt of Congress for officials who defy subpoenas has to be referred to the Justice Department, which has long had discretion over whether to prosecute. The department sits in the executive branch, which Congress does not control.

Mary Trump's Message to U.S. Allies

"They need to disabuse themselves of the notion that capitulating to him is going to get them anything, because clearly they've tried that," she said of Western governments. "He goes against his word. He does whatever he wants to do anyway."

She added: "He is much more aligned with Putin and Kim Jong Un than he is with any of our NATO allies."

The record is mixed. In June 2025, Canada dropped its digital services tax to get stalled trade talks restarted. In October 2025, the president ended the talks again over an Ontario TV ad that quoted Ronald Reagan, and he said he would add a 10 percent tariff.

But the European Union's July 2025 deal set a 15 percent tariff on most of its goods. That was half the 30 percent rate the president had threatened.

What Happens Next

Mary Trump said world leaders must "recognize that the only way to mitigate the damage he's doing is to try to stop him at every turn and not give in to him."

The election is less than two weeks away. It will settle which chamber, if either, gets the tools she is counting on. How far those tools reach will be tested after that.
