Former special counsel Mueller will testify before Congress about his report on investigation into Russia’s election interference on July 17, following a subpoena. House Democrats said on Tuesday, June 25.

He will publicly testify before the House Judiciary and Intelligence Committees.

Rep. Jerrold Nadler (D-N.Y.), the chair of the Judiciary Committee and Rep. Adam Schiff (D-Calif.) the chair of the Intelligence committee, said In a joint statement, “Pursuant to subpoenas issued by the House Judiciary and House Permanent Select Committee on Intelligence tonight, Special Counsel Robert S. Mueller III has agreed to testify before both Committees on July 17 in open session.”

“Americans have demanded to hear directly from the Special Counsel so they can understand what he and his team examined, uncovered, and determined about Russia’s attack on our democracy, the Trump campaign’s acceptance and use of that help, and President Trump and his associates’ obstruction of the investigation into that attack,” Nadler and Schiff’s statement said.

After Mueller finished the official report in March, he concluded that nobody associated with President Trump’s campaign “conspired or knowingly coordinated” with Russia during the 2016 presidential election. Attorney General William Barr reviewed the report and determined that it was insufficient to accuse President Trump of criminal wrongdoing, saying he did not see enough evidence to charge President Trump with obstruction of justice. President Trump has welcomed the result and tweeted multiples times “No collusion, No obstruction”

When William Barr announced there was no collusion or obstruction committed by President Trump, Democrats repeatedly wanted more evidence on the report, saying that the findings were still unclear and that Congress must hear from Mueller in order to better understand the results.

Democrats have been waiting for Mueller to testify before Congress could delve more into the report since Mueller completed his nearly two-year investigation in March. For several weeks, both committees had been negotiating for Mueller’s voluntary appearance but had not reached an agreement. Mueller had seemed unwillingly to testify publicly before Congress in his first public remarks on his investigation into Russia’s election interference last month.

At a press conference at the Department of Justice on May 29, Mueller defended his 448-page report, saying that “insufficient evidence to charge a broader conspiracy,”

“The report is my testimony,” he said.

“There has been a discussion about an appearance before Congress. Any testimony from this office would not go beyond our report,” Mueller said.

Next month, lawmakers from Democrats and Republicans will have the unique chance of questioning Mueller publicly before Congress, hoping that his answers will clarify the unclear findings for both sides.

President Trump has reacted to this news with a tweet that said, “Presidential Harassment!”
