Republican Senator Bill Cassidy is now vocally opposing President Trump after losing his primary election last week thanks to the president’s endorsement of one of his opponents.On Wednesday, Cassidy held nothing back in criticizing the White House ballroom Trump is building, complaining in particular about the president’s lack of transparency.“There’s no architectural plans. There is no environmentals. There’s no engineering. There’s no sense of when we ask, how did it happen to cost exactly a billion,” Cassidy told CNN. “It could cost a lot less, it could cost a lot more, I just don’t get it.” Cassidy on ballroom: There's no architectural plans.

This is adding to our national debt. If there needs to be a settlement, the administration should bring it to Congress to decide,” Cassidy said in a post on X about the fund, created from a settlement agreement between Trump and the IRS.It’s telling that Cassidy only feels emboldened to speak out once his political career is essentially over. He had plenty of earlier opportunities to publicly oppose Trump’s policies, especially considering he is a medical doctor and has seen some of the White House’s destructive public health decisions.Instead, Cassidy voted to confirm Robert F. Kennedy Jr., a well-known anti-vaccine activist, as secretary of health and human services, and has refused to address Kennedy’s weakening of vaccine policies since then. In the end, it didn’t help him politically, as Trump still criticized him and backed Representative Julia Letlow in the Louisiana Senate Republican primary. Now he’s pretending to have some courage.
