President Donald Trump lambasted socialism during his State of the Union address on Tuesday night, prompting cheers and chants of “USA, USA” from Republicans in the chamber. But at least one lawmaker didn’t seem too pleased by the diss: Bernie Sanders, the independent senator from Vermont. After criticizing embattled Venezuelan leader Nicolás Maduro’s “socialist policies” as being the cause of the South American country’s “abject poverty and despair,” Trump said he was “alarmed by the new calls to adopt socialism” in the United States — a statement that prompted some boos from his audience. The president continued: “America was founded on liberty and independence and not government coercion, domination and control. We are born free and we will stay free.” “Tonight, we renew our resolve that America will never be a socialist country,” he added after a pause.

Cheers and applause erupted in the room as network cameras zoomed in on Sanders’ face. The 77-year-old senator, who has described himself as a democratic socialist, appeared to frown, his lips tightly pursed.

"We are alarmed by the calls to adopt socialism in our country," Pres. Trump says.

Sanders, who issued a rebuttal to Trump’s SOTU address, later pushed back against Trump’s remarks. “Trump said tonight, ‘We are born free, and we will stay free.’ I say to Trump: People are not truly free when they can’t afford health care, prescription drugs, or a place to live. People are not free when they cannot retire with dignity or feed their families,” he wrote on Twitter.
