That explanation is: “We have a crud Republican-controlled Congress.”
It doesn’t matter what the explanation is. I just don’t want people who are not very tuned in to politics to find out that they will pay taxes on their Social Security next year while they’re filing their taxes. That is too close to the election. Many of them will just stay home because they will be angry at Trump. They need to find out now so there is plenty of time before the 2026 election. As of a few days ago, Trump was still saying “no taxes on Social Security.”
