Shortly after Pelosi's announcement, Lizzo jokingly tweeted the word impeachment including an emoji of a peach.

"Truth hurts," Castro, who has previously voiced support for impeaching Trump, said in a tweet linking to the pop star's and using the name of one of her biggest hits.

Amid mounting scrutiny over Trump's interactions with Ukrainian President Volodymyr Zelensky, Pelosi announced Tuesday afternoon that the House was prepared to launch impeachment proceedings.

“Our republic endures because of the wisdom of our Constitution enshrined in three coequal branches that act as checks and balances,” Pelosi said. “The president must be held accountable. No one is above the law.”

The decision marked a significant shift for the Speaker, who had long resisted increasing calls from lawmakers to start impeachment. The decision comes just a week after reports first surfaced that Trump pressured the leader of Ukraine in a July phone call to investigate the son of 2020 presidential candidate and former Vice President Joe Biden Joe BidenFormer Pence aide: White House staffers discussed Trump refusing to leave office Progressive group buys domain name of Trump's No. 1 Supreme Court pick Bloomberg rolls out M ad buy to boost Biden in Florida MORE over allegations of corruption.

The discussion occurred around the same time the administration delayed hundreds of millions of dollars in military aid to Ukraine, raising speculation from Democrats as to whether the president used the aid as leverage in the talks.

Trump has acknowledged speaking over the phone with Zelensky about Biden but has denied bringing up military aid in his talks with the leader. Earlier Tuesday, Trump said he had authorized the release of the transcript of their discussion.

The developments led to a substantial increase in the number of Democrats voicing support for impeachment. Castro has been one of many Democrats calling for Congress to take action against the president.

"Pelosi is right," he said on Twitter following Pelosi's announcement. "No one is above the law. I support House Democrats in launching a formal impeachment inquiry."
