U.S. Secretary of State Mike Pompeo will testify before Congress to discuss Russia next week, the Republican chair of the U.S. Senate Foreign Relations Committee told reporters on Tuesday, Reuters reported.

U.S. Senator Bob Corker did not give a specific date for the hearing, which comes after U.S. President Donald Trump’s summit with Russian President Vladimir Putin in Helsinki on Monday. Representatives for the State Department had no immediate comment on the congressional hearing.
