President Obama said the FBI is investigating Monday's twin bombings at the Boston Marathon "as an act of terrorism." Meanwhile, law enforcement officials are asking the public to submit photos and videos from the scene. And Boston Mayor Tom Menino said that as the city grieves the victims it is also proud of those who helped in the explosions' aftermath.
The nation's capital has been undergoing something of a building boom. Dozens of construction cranes dot the Washington, D.C., skyline.
So it comes as no surprise that the federal government is hoping to take advantage of the real estate values and unload what's seen by many as an eyesore on Pennsylvania Avenue: the J. Edgar Hoover Building, headquarters of the FBI.
Robert Mueller became FBI director just days before the attacks of Sept. 11, 2001. Since then, he's been the U.S. government's indispensable man when it comes to national security.
But Mueller's term has expired, and the clock is ticking on an unprecedented extension that Congress gave him two years ago.
The first time the Obama White House thought about a replacement for Mueller, back in 2011, officials threw up their hands and wound up begging him to stay. Congress passed a special law to allow it. Then Republican Sen. Charles Grassley of Iowa put his foot down.
