The Democratic-led U.S. House Judiciary Committee on Wednesday, Aug. 7, filed suit to compel former White House counsel Don McGahn’s testimony, arguing that the committee needs to hear from him to decide whether to recommend the impeachment against the President Donald Trump.

“McGahn … is the most important witness, other than the president, to the key events that are the focus of the Judiciary Committee’s investigation,” the lawsuit said.

The move represented the latest step toward impeachment by Democrats in the House in the hope that could put things back on track as House Democratic leaders faced growing pressure with the outcome of Mueller’s testimony in July. Currently, 118 of the 235 Democrats in the House have voiced support for starting the inquiry.

“The Judiciary Committee is now determining whether to recommend articles of impeachment against the president based on the obstructive conduct described by the special counsel,” the House said in its new lawsuit. “But it cannot fulfill this most solemn constitutional responsibility without hearing testimony from a crucial witness to these events: former White House Counsel Donald F. McGahn II.”

Republicans condemned the lawsuit as a theatrical gesture Democrats seek to gain more public’s attention.

“Democrats’ decision to unilaterally end the accommodations process and file a lawsuit serves only to shut off this committee’s access to White House and DOJ documents. Their insistence on having Don McGahn testify publicly before the cameras further proves they are only interested in the fight and public spectacle of an investigation, but not actually in obtaining any real information,” Rep. Doug Collins (R-Ga.) the panel’s top Republican said in a statement.

Polls showed that a majority of Americans as well as Democrats in tough districts do not favor impeachment. Instead, they say they’re more focused on other issues that matter more to Americans.
