A group of Democratic US senators warned Monday that congressional Republicans and President Donald Trump could be gearing up for a push for raise the retirement age as part of a broader—and deeply unpopular—effort to slash Social Security benefits after the 2026 midterm elections.Sens. Elizabeth Warren (D-Mass.), Tammy Duckworth (D-Ill.), and Richard Blumenthal (D-Conn.) wrote in a letter to Trump that they have “renewed concerns” that his administration is “considering raising the retirement age, cutting the earned benefits of millions of Americans,” despite the president’s repeated vows to shield the program.“Republicans have a history of attempting to increase the retirement age, privatize Social Security, or otherwise cut Social Security benefits, and some congressional Republicans have called to raise the retirement age or means-test benefits,” the lawmakers wrote, emphasizing that GOP lawmakers “are not alone.”“In an interview this past fall, [Social Security Administration] Commissioner Frank Bisignano said—and later attempted to retract after public outcry—that your administration was considering this idea,” the Democratic senators wrote of raising the retirement age, which would cut Social Security benefits across the board.The nonpartisan Congressional Budget Office analysis of a 2024 Republican proposal to raise Social Security’s full retirement age found that doing so would cut benefits by an average of 13% for people born after 1971.The Democratic senators sent their letter to Trump days after Social Security’s trustees said in their annual report that the program will be unable to pay out full benefits by the end of 2032—a quarter earlier than projected last year—unless Congress takes action. The finding was seen as evidence of the damage inflicted by Trump’s policies, including his tariffs and tax cuts for the rich.Ahead of the trustees report’s release, House Speaker Mike Johnson declared that Social Security needs to be “adjusted and fixed” and said Republicans would release their plan “next year,” without specifying what the proposal would entail.In their letter to Trump on Monday, the trio of Democratic senators demanded to know if the president is aware of “Republican plans to cut Medicare, Medicaid, or Social Security benefits” and whether he would veto GOP legislation that slashes those programs.“Raising the retirement age—or otherwise cutting benefits—only worsens the looming retirement income crisis,” the lawmakers wrote. “Doing so hurts older Americans, cutting monthly benefits and forcing millions into poverty.”
