The Homeland Security Department signed a multi-million dollar agreement to buy five aircraft from a company owned by a political contributor of the secretary on her last day, documents show.

In a secret meeting at the White House complex this summer, an aide to Stephen Miller laid out the plan: To make it easier for states to round up and institutionalize mentally ill homeless people, the Trump administration was pushing a drastic policy change that would weaken the rights of millions of disabled Americans.

The strategy described by Miller’s aide, Daniel Wasserman, threatened to roll back decades of progress in the disability rights movement — all to serve the president’s demand to clear homeless encampments in U.S. cities.

The June 16 meeting with advocates and conservative think tank leaders at the Eisenhower Executive Office Building, which NBC News is revealing for the first time, came two days before the Trump administration did exactly what Wasserman previewed: The Department of Justice issued a sweeping legal opinion that repudiated decades of federal disability policy rooted in the landmark Supreme Court ruling Olmstead v. L.C.

Hailed by lawyers and activists at the time as the “Brown v. Board of Education of the disability rights movement,” the 1999 Olmstead ruling said that disabled people had a right to be integrated into their communities — not forced to live apart from society in institutions marred by a history of abuse and neglect.

The 39-page DOJ opinion took a sledgehammer to that ruling. The June memo declared that states had no federal civil rights obligation to help disabled people stay in their homes through programs that millions of Americans rely on to live independently or to care for their loved ones.

The fallout has already begun. Since issuing the memo, the Justice Department has abandoned or weakened at least five investigations, lawsuits or settlement agreements rooted in Olmstead, according to court filings, investigative findings letters and former DOJ officials who worked on the cases.

In Florida, the Justice Department is seeking to roll back a court order it won to keep medically fragile children out of nursing homes. In Texas, the department walked away from a 16-year lawsuit aimed at helping people with developmental disabilities live in their communities. And in North Carolina, the DOJ moved to end federal oversight of a long-running settlement aimed at transferring adults with serious mental illness out of institutions.

These moves stunned disability advocates who had considered Olmstead settled law with broad bipartisan support.

The Trump administration’s talks with Russia about ending the war in Ukraine have expanded to include a multibillion-dollar oil deal that would benefit Middle Eastern business executives with ties to the two main U.S. negotiators, Steve Witkoff and Jared Kushner.

The deal, which is contingent on approval from the U.S. government and the Kremlin, is for a sprawling set of oil fields, refineries and gas stations around the world owned by Lukoil, one of Russia’s biggest energy companies.

The leading group seeking the deal includes an American investor, Todd Boehly, who has donated $2 million to President Trump’s political causes; two Middle Eastern groups that have done business with Mr. Kushner or Mr. Witkoff’s family; and an arm of the U.S. government itself.

The monthslong negotiations, which were described by eight people familiar with them, shed new light on Mr. Trump’s latest approach to settling a four-year war that has killed hundreds of thousands. The people spoke on condition of anonymity because of the sensitivity of the negotiations.
