U.S. Rep. Diana DeGette, a Denver Democrat, said Tuesday that she won’t attend President Donald Trump’s address to a joint session of Congress. She called Trump’s actions since taking office “beneath the office of the president.”

Instead, DeGette said she planned to watch the speech closely and vowed to “continue to call out Trump’s lies and stand up for the truth.”

Trump was scheduled to deliver a speech on what the White House described as the “renewal of the American dream” Tuesday night before what’s expected to be a packed House chamber just over six weeks after the Republican’s inauguration to a second term.

DeGette said in a statement that she decided to boycott the speech in response to Trump’s confrontational Oval Office meeting last week with Ukrainian President Volodymyr Zelenskyy and the administration’s “barrage of illegal attacks against public servants and vulnerable groups.”

Trump and Vice President JD Vance engaged in a drawn-out, tense exchange with Zelenskyy. They ejected the wartime leader from the White House instead of consummating a deal meant to facilitate negotiations to bring an end to Russia’s three-year-old invasion of the American ally.

Since taking office, Trump and his administration have made a sweeping effort to slash federal spending, including dismantling some federal agencies and firing employees.

“As Trump undermines our democracy and assaults the values we hold dear, he continues to ignore his promise to lower costs and make life better for the American people,” DeGette said.

House Minority Leader Hakeem Jeffries, a New York Democrat, on Monday urged his fellow lawmakers to have a “strong, determined and dignified” presence at Trump’s speech but added in a “dear colleague” letter that the decision whether to attend the joint session was “a personal one and we understand that members will come to different conclusions.”

Jeffries said the party’s leadership planned to attend the speech “to make clear to the nation that there is a strong opposition party ready, willing and able to serve as a check and balance on the excesses of the administration.”

Numerous Democratic lawmakers, however, announced that they wouldn’t be in the chamber, including New York Rep. Alexandria Ocasio-Cortez, Virginia Rep. Gerry Connolly and Washington Sen. Patty Murray.

The speech is set to start at 7 p.m. Mountain Time and will be broadcast and streamed on multiple platforms.
