“What have Republicans in the Senate been doing since the very day that Barack Obama Barack Hussein ObamaObama calls on Senate not to fill Ginsburg's vacancy until after election Senate Republicans face tough decision on replacing Ginsburg Cruz: Trump should nominate a Supreme Court justice next week MORE was sworn in?” she said in an interview with MSNBC’s Rachel Maddow, the Massachusetts senator’s first television appearance since the beginning of the presidential race. “They have given in to their extremists; in fact, they have nursed their extremists along.”

“They are paying the price for their own extremism,” she added in a reference to Trump's popularity, which has shocked much of the GOP.

Warren slamed Senate Republicans for a “shutdown approach” to legislating that she said extended to their refusal to grant a vote to anyone nominated by Obama to the Supreme Court.

She then linked that approach to Trump's popularity.

“Guys, this is what you did to yourselves,” Warren said of Senate Republicans. “And if you really want to stop it, stand up and do your jobs.”

Though the liberal firebrand refused to endorse a candidate Thursday night, she delighted in contrasting between the her party’s presidential race and that of the GOP.

“We’re out there talking about — both of our candidates are talking about — of holding Wall Street accountable,” Warren said. “We’re having a debate back and forth about the best way to make sure our kids can make it through college without getting crushed by student loan debt.”

“We’re doing what Democrats should be doing,” she added. “We’re talking about the issues, and more than anything else we’re talking about who it is that we want government to work for. And boy, does that make a contrast with what’s going on on the other side.”
