Democrats announced on Tuesday that special counsel Robert Mueller had agreed to testify before Congress about his investigation and report into Russian election interference.

House Judiciary Chairman Rep. Jerry Nadler (D-N.Y.) tweeted an announcement about the scheduled testimony.

"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," Nadler said in the statement.

"Americanshavedemanded 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," Nadler continued, "the Trump campaign's acceptance and use of that help, and President Trump and his associates' obstruction of the investigation into that attack.

"We look forward to hearing his testimony, as do all Americans," Nadler concluded.

Rep. Adam Schiff (D-Calif.) confirmed the news from his Twitter account.

"Russia attacked our democracy to help Trump win. Trump welcomed and used that help," Schiff tweeted. "As Mueller said, that should concern every American. And now, every American will get to hear directly from Mueller."

Democrats have charged that Mueller's report implied a recommendation to Congress to impeach President Donald Trump over accusations of obstruction of justice.

Republicans and other allies of the president interpreted the report to say that if there was evidence of wrongdoing against Trump that Mueller would have charged him.

The issue may be resolved when Mueller testifies on July 17.
