Michael Cohen, President Trump's former personal lawyer, will testify before a congressional committee on February 27, the panel announced Wednesday. He is now scheduled to report to jail May 6.
"Congress has an independent duty under the Constitution to conduct oversight of the Executive Branch, and any efforts to intimidate family members or pressure witnesses will not be tolerated", House Speaker Nancy Pelosi tweeted.
After testifying publicly on Capitol Hill next Wednesday, Feb. 27, Cohen is then scheduled appear in a closed session before the House intelligence committee the next day.
Trump has fumed to advisers about a search by federal prosecutors of his lawyer and former fixer Michael Cohen's office and residences in April 2018, and those close to Trump have feared the investigation into Cohen could extend deeper into Trump's business.
Cohen is also scheduled to testify at a closed hearing of the House Intelligence Committee on February 28.
Last week, Cohen's lawyers said he was delaying his Senate testimony "due to post-surgery medical needs".

The administration's move comes amid escalating tensions between it and Democratic leaders of the most populous US state. The agreement does not require the California High-Speed Rail Authority to build trains for the track.
Cohen told lawmakers in 2017 that he had abandoned a Trump business proposal in Moscow in January 2016, but he later acknowledged he continued pursuing it for months after that.
Cohen was originally scheduled to report to jail on March 6 to begin serving a three-year sentence after he pleaded guilty to campaign finance and other violations last year.
As federal prosecutors in Manhattan gathered evidence late previous year about President Trump's role in silencing women with hush payments during the 2016 campaign, Mr. Trump called Matthew G. Whitaker, his newly installed attorney general, with a question. Among the crimes was a hush-money scheme meant to silence women who said they had affairs with Trump.
In the request for a delay dated Wednesday, Cohen's attorney, Michael D. Monico, cited a "more fulsome letter" sent to Pauley eight days ago by Cohen that was sealed.
In response to Trump's tweet, Times publisher A.G. Sulzberger said in a statement that "there are mounting signs that [Trump's] incendiary rhetoric is encouraging threats and violence against journalists at home and overseas". "In addition, he will be able to prepare for the expected testimony next week before congressional committees, which he welcomes".
