Donald Trump doesn't even have concepts of a plan for Venezuela, but he's already briefed big oil executives on how they make money from his invasion. Once again, he's prioritizing himself and his billionaire buddies over our democracy and the American people. apnews.com/article/trum...
This regime wants to transfer ED programs to federal agencies with no education experience or expertise. They've already tried this before and realized on their own that it does not work. Yet they are doing it again. Why? Because they do not care about your kids.
This does not have to happen. There is a vaccine to prevent whooping cough, but this regime prioritizes conspiracy theories over your health. Americans deserve to be healthy, not plagued with PREVENTABLE illnesses.
Republicans are doing what they do best: deflecting. Instead of finding a solution to the health care crisis they created, they want to distract you from the truth: health care costs are skyrocketing, and it's all their fault. www.politico.com/news/2025/12...
Protecting child health apparently no longer "aligns" with HHS's "missions or priorities". HHS just confirmed what I've been saying for months: This regime does not prioritize keeping our children or our nation healthy. www.washingtonpost.com/health/2025/...
Republicans love to talk about rooting out waste, fraud, and abuse. But why don't any of them pay attention to the rampant waste, fraud, and abuse coming from Trump? It's not like his lawlessness and abuse of power are hard to see.
Now that Trump’s gaudy ballroom is on the line, this administration suddenly claims to care about national security. Where was that concern when Pete Hegseth was using Signal to share details of a classified mission?
Republicans voted to make life cheaper for the ultra-wealthy in more ways than one, but won't vote to make health care costs more affordable for working Americans. How sad and messed up is that?
This is fear-mongering. This regime wants you to fear the vaccines that keep you, your family, and your communities safe and believe junk science and conspiracy theories over proven science. This decision is dangerous. www.cnn.com/2025/12/12/h...
This regime hands out tax breaks to billionaires and major corporations while forcing costs to skyrocket for working Americans. The rich get richer while the rest of America struggles to get by. That is the reality of Trump's economy.
America is one of the richest countries, yet Americans pay more for their health care than anywhere else. There is no reason that should be the case. Yet once again, when given the chance to lower costs, Republicans chose to force costs to skyrocket over voting with Democrats.
