WASHINGTON (AP) — President Barack Obama will issue a statement on the explosions at the Boston Marathon in televised remarks to the nation from the White House.
Obama was briefed on Monday's explosions by FBI Director Robert Mueller and Homeland Security Secretary Janet Napolitano. The White House said the president also spoke with Massachusetts Gov. Deval Patrick and Boston Mayor Tom Menino and pledged to provide whatever federal support was needed in responding to the incident.
Additionally, the president spoke with House Speaker John Boehner, R-Ohio, shortly before his remarks to the nation.
As the president was being briefed on the incident, the Secret Service quickly expanded its security perimeter at the White House. The agency shut down Pennsylvania Avenue and cordoned off the area with yellow police tape. Several Secret Service patrol cars also blocked off the entry points to the road.
The White House was not on lockdown and tourists and other onlookers were still able to be in the park across the street from the executive mansion.
