Im not getting how trump can fire anyone? Does he have the authority to do that?

The US government is not currently in a state of following the law or constitution. People get fired, and if authority was not there, a lawsuit 9-18 months later might rectify it, and in the meantime the fired employee has moved on. DOGE cuts were extreme, capricious, and the only rhyme or reason was to try to hyperpoliticize the science to meet what people were guessing that Trump would want. On the grant side, they cut grants in an explictly racist way, according to a Reagan-appointed Republican judge that ruled aganist them way back in June of 2025; what was the remedy? Merely to reinstate the grants.

Who is going to stop a lawless Trump administration? Eventually the courts, at least at the lower levers. The Supreme Court is hyper political and continue making politically-driven rewriting of law, at least as much as the public lets them. Congress has completely abdicated their constitutionally mandated roles, such as being in charge of taxation and tariffs. The government has been completely taken over by a single party, and that party is burning the Constitution and its principles.

As for another example of gross mismanagment, of many many many more I could go on about, the National Cancer Institute's review board was completely disbanded, and put under the National Science Foundation where reviewers have less cancer experience, for example. To a pointy-haired-boss, that might sound like a cost savings measure but it's still the same cost, you just have less experienced people doing reviews.

All this is happening and getting reported on, but it doesn't get attention because every day is pure chaos filled with outrageous violations of what used to be normal activity in the government. And its all covered up by the most popular mainstream news sources, and there's a large body of the US population that has been completely brainwashed and literally refuses to accept any criticism of the Trump administration, outright rejected facts because it hurts their feelings.
