Schumer has defended his vote to keep the government running as the best of two bad choices aimed at not ceding Trump and billionaire adviser Elon Musk even more power to slash the government. Nine Democratic senators and an independent who caucuses with Democrats joined him to advance the bill, enough to prevent a government shutdown.

After weeks of frustration with President Donald Trump, the Democratic base has turned its ire on a new target: Senate Minority Leader Chuck Schumer and the 10 Democratic senators who voted to advance a Republican funding bill rather than shut down the government.
