Alexandria Ocasio-Cortez slammed House Democrats for not moving forward on impeachment proceedings against President Donald Trump, claiming that their unwillingness to oust the president is more scandalous than his behavior.

“At this point, the bigger national scandal isn’t the president’s lawbreaking behavior—it is the Democratic Party’s refusal to impeach him for it,” she said in a tweet, which prompted some of her fellow Democrats to say that it’s a false equivalence.

“It is one thing for a sitting president to break the law. It’s another to let him. The integrity of our democracy isn’t threatened when a president breaks the law. It’s threatened when we do nothing about it,” the congresswoman replied to the criticism. “The GOP’s silence & refusal to act shouldn’t be a surprise. Ours is.”

The freshman lawmaker later doubled down on the issue by retweeting other Democrats who also joined the chorus of outrage.

Democratic presidential candidate Beto O’Rourke tweeted, “What is Congress waiting for? This is crazy. Unless we take action now, we will see the end of American democracy.”

“For the sake of our Constitution, and for the sake of our country,” Rep. Brendan Boyle (D-Pa.) tweeted, “Donald Trump must be impeached, convicted in the Senate, removed from office, and face criminal trial.”

Democratic presidential candidate Sen. Elizabeth Warren (D-Mass.) also took to Twitter, accusing Congress of being “complicit” with the president.

“After the Mueller report, Congress had a duty to begin impeachment. By falling to act, Congress is complicit in Trump’s latest attempt to solicit foreign interference to aid him in the U.S. elections. Do your constitutional duty and impeach the president,” she wrote.

The Democrats’ call for impeachment followed a tumultuous week of a controversial whistleblower complaint against President Trump who allegedly pressed Ukrainian president to investigate former Vice President Joe Biden’s son and forced him to intervene in the 2020 U.S. presidential election.

Biden has called for a new investigation in the House while three Democrat-led committees have already launched a probe into alleged efforts by the president and his lawyer Rudy Giuliani to force the Ukrainian government for their own political ends.

House Democrats are trying their level best to move forward on impeachment charges, especially after former special counsel Robert Mueller with his two-year Russia investigation, failed to find criminal conspiracy between the Trump campaign and the Kremlin.

Democrats used the whistleblower’s complaint to fuel the impeachment proceedings. CNBC’s John Harwood wondered if “the whistleblower/Ukraine” could change House Speaker Nancy Pelosi’s “view on potential Trump impeachment?”

However, Pelosi seemed not to change her mind, saying it would be “a divisive approach.” She resisted a formal House vote allowing the launch of an official impeachment inquiry.

House Judiciary Committee Chairman Jerry Nadler (D-N.Y.) suggested an official investigation is underway. Pelosi said she supports Nadler but stopped short of backing his claim.
