“That American Dream is increasingly out of reach for far too many people, especially younger Americans,” Trump said on social media, referring to home ownership.

“People live in homes, not corporations.”

The White House did not immediately respond to a request for comment on the details of a possible ban, including whether it would require congressional approval.

Trump’s comments on Wednesday come as his administration faces growing public pessimism about his handling of the economy. He has in recent weeks sought to allay voter anxiety about the cost of living in the US, with home affordability high on the list of Americans’ concerns.

Sam Garin, a spokesperson for an advocacy group that has raised alarm about the effect of private equity ownership on renters, said her group welcomed Trump’s move.

“We eagerly await the details of what this policy will actually entail,” said Garin, of the Private Equity Stakeholder Project, adding: “But we urge policymakers not to stop there.”

Since the 2008 financial crisis led to a wave of foreclosures, Wall Street investors such as Blackstone and other private equity firms have bought tens of thousands of homes to rent out, becoming major landlords, especially in certain markets.

Their role has drawn scrutiny from lawmakers in both political parties, who have blamed the firms for helping to push up the cost of renting and buying. But previous legislative efforts have gained little traction.

“Senate Democrats tried to do this last year. Republicans blocked it,” Senate Minority Leader Chuck Schumer, a Democrat, said on social media.

On Wednesday, Ohio Republican Senator Bernie Moreno said he would introduce legislation to codify Trump’s proposal.
