evidence: WASHINGTON — A new budget by a large and influential group of House Republicans calls for raising the Social Security retirement age for future retirees and restructuring Medicare. The proposals, which are unlikely to become law this year, reflect how many Republicans will seek to govern if they win the 2024 elections. And they play into a fight President Joe Biden is seeking to have with former President Donald Trump and the Republican Party as he runs for re-election. [...] For Social Security, the budget endorses "modest adjustments to the retirement age for future retirees to account for increases in life expectancy." It calls for lowering benefits for the highest-earning beneficiaries. And it emphasizes that those ideas are not designed to take effect immediately: "The RSC Budget does not cut or delay retirement benefits for any senior in or near retirement."
