Washington: Former special counsel Robert Mueller will testify to Congress in open session next month about his investigation of Russia's interference in the 2016 election and possible obstruction of justice by President Donald Trump.

The House Judiciary and Intelligence committees, in a late-night announcement on Tuesday, said that "pursuant to a subpoena" Mueller has agreed to appear before both panels on July 17.

"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," said House Judiciary Committee Chairman Jerrold Nadler, and House Intelligence Committee Chairman Adam Schiff in a statement.

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