A day ahead of the one-year anniversary President Donald Trump’s inauguration, Sen. Bernie Sanders (I-Vt.) on Friday sharply criticized the president’s performance during his first year in office, calling him “an international embarrassment” in an interview on MSNBC.

“Has it really only been one year? I thought it was about 16 years,” Sanders joked, before outlining how Trump has departed from his campaign promises during his presidency.

Trump “is a pathological liar…who ran on a populist campaign,” Sanders charged. “He said, ‘healthcare for everybody,’ he’s going to stand up to Wall Street, he’s going to stand up to the drug companies. He lied.”
