“All Americans should be deeply concerned by the reports that Russian agencies have interfered with a U.S. election. As Speaker Ryan noted, ‘any foreign intervention in our elections is entirely unacceptable.’

“The first duty of the United States government is to safeguard the American people and the integrity of our free society from attacks by foreign adversaries. Cyberattacks on our political institutions are direct threats to their integrity and are just as menacing as attacks on our economic, physical, and military infrastructure.

“Given the gravity of these unprecedented attacks by a foreign state, we need a congressional investigation that is truly bipartisan, that is comprehensive, that will not be restricted by jurisdictional lines, and that will give the American people a complete and full accounting of what happened consistent with safeguarding our national security.”
