WASHINGTON -- The Obama administration is considering filing the first criminal charges against radical cleric Anwar al-Awlaki in case the CIA fails to kill him and he is captured alive in Yemen. The decision continues the White House's strategy of fighting terrorism both in courthouses and on battlefields.

Al-Awlaki, a U.S. and Yemeni citizen born in New Mexico, has inspired a wave of attempted attacks against the United States and has become Al Qaeda's leading English-speaking voice for recruiting and motivating terrorists. Counterterror officials said al-Awlaki, since mid-2009, has become a major operational figure who selects targets and gives orders.
