The nonprofit Free Speech for People, which is leading a nonpartisan campaign to drum up support for an impeachment investigation into U.S. President Donald Trump’s conduct, announced Friday that it has gathered more than 250,000 petition signatures.

The campaign, called “Impeach Trump. Again.,” was launched its petition on Inauguration Day. Free Speech for People also launched a campaign to build public support for Trump’s impeachment on the day of his inauguration back in 2017.

Trump was impeached twice by the House of Representatives during his first term, but in both cases he was acquitted by the Senate. Both chambers of Congress are now controlled by Trump’s Republican Party.

“The Constitution has a remedy for a corrupt, lawless president: impeachment,” said John Bonifaz, president of Free Speech For People, in a statement Friday announcing the petition signatures.

Last month, Rep. Al Green (D-Texas) announced on the floor of the House of Representatives that he intends to bring articles of impeachment against Trump and Trump suggested that the United States take over the Gaza Strip—a proposal that Free Speech for People includes on its list of the president’s alleged “abuses of power.”

“The movement to impeach the president has begun,” Green said at the time, according to The Hill. “I rise to announce that I will bring articles of impeachment against the president for dastardly deeds proposed and dastardly deeds done.”

Leadership with Free Speech for People praised Green’s pledge to file articles of impeachment.

“We applaud Congressman Al Green for demanding that the U.S. Congress hold Donald Trump accountable through the impeachment process for his dangerous abuses of power,” said Courtney Hostetler, Free Speech for People’s legal director.

“As Trump repeatedly undermines our democracy and ignores the Constitution, we will continue to call on Congress to fulfill its duty by investigating and, if necessary, removing this corrupt executive from office,” Hostetler continued.

Green recently made headlines for disrupting the Trump’s address to a joint session of Congress on Tuesday, telling the president he had “no mandate to cut Medicaid,” a move he was later censured for by the Republican-controlled House of Representatives.

Free Speech for People wants Congress to launch an impeachment investigation into Trump for “abusing his power to seek retribution against perceived adversaries” and “unconstitutionally usurping Congress’s powers,” among other alleged offenses.
