Congress has lots of power, it's a question of whether they do anything. Currently the Republicans are uniformity falling in line with the authoritarian executive orders, even those that abrogate well established congressional powers.
Remember we are still in the first 100 days. Congress typically falls in line for the first few months (not always 100 days, but it is a good round number). As the term goes on though congress tends to start looking to the next election and they start to opposed unpopular things because they will lose in 2 years. Trump is risking a democrat super majority in the house in 2 years if he is too unpopular, and 20 republicans are up for election in the senate, if even half of them turn that would be a majority for the democrats and a shot that the other republican senators (who want to win election in 2-4 more years) will pay attention to.
But we need to get through the first few months before any of this will play out. And after that there is still a long time before the 2026 elections.
