WASHINGTON (AP) — An ally of House Speaker Nancy Pelosi and a Democrat who flipped a Republican district are joining a slowly growing group calling for impeachment proceedings against President Donald Trump.

Rep. Jan Schakowsky, a congressional veteran, said in a Twitter video that Trump “certainly has committed all kinds of offenses that meet the standard” for a formal charge by the House. Rep. Sean Casten told the Chicago Sun-Times that he wants Congress to use “every tool” to investigate Trump, even if that means paying a political price in the 2020 elections.

The two Illinois lawmakers spoke out on the same day Hope Hicks refused to answer House Judiciary Committee questions about Trump during his presidency, highlighting a slowly growing chorus of calls from more than 60 House members for an impeachment inquiry. But most Democrats still oppose such a move. And Pelosi has resisted launching official proceedings without broad bipartisan support.

On Wednesday night, Schakowsky left that camp.

“The House of Representatives should begin an impeachment inquiry officially, because President Trump certainly has committed all kinds of offenses that meet the standard of impeachment,” she said in the tweeted video.

Casten on the same day set himself apart from many of the Democrats’ most vulnerable freshmen who helped flip the House from Republican control in 2018.

“I am in favor of initiating an impeachment inquiry,” he told the Chicago Sun-Times in remarks confirmed by a spokeswoman.

Both Illinois lawmakers said launching an impeachment inquiry would give the House more legal strength to compel information from a president who has vowed not to cooperate.
