California Republican Rep. Ed Royce, chairman of the House Foreign Affairs Committee, said it was a “terrorist attack” and “yet another stark reminder that we must remain vigilant in the face of continuing terrorist threats.”
The White House said Obama refrained from publicly calling the attacks terrorism because it was early in the investigation and the perpetrators were unknown. But the official said any time there is an event with multiple explosions going off at the same time and aimed at hurting people, the administration considers that terrorism.
The president was briefed on the incident Monday by several senior administration officials, including FBI Director Robert Mueller and Homeland Security Secretary Janet Napolitano. He also spoke with Massachusetts Gov. Deval Patrick and Boston Mayor Tom Menino and pledged to provide whatever federal support was needed.
