President Obama tweeted support for U.S military troops in Libya Tuesday, echoing Monday night’s address to the nation.

“Thanks to our men and women in uniform and our dedicated diplomats, a coalition has been forged and countless Libyan lives have been saved,” Obama tweeted.

Obama's tweet echoed the speech he delivered at the National Defense University Monday night in which he defended his decision for the U.S. to join in the enforcement of a United Nations Security Council no-fly zone resolution in Libya.

Since the U.S. has participated in the multinational no-fly zone effort, Obama has been criticized by lawmakers across the political spectrum for going into Libya without an exit strategy or clearly stated mission and for failing to first seek congressional approval for the mission.

In Monday's speech, Obama’s first in-depth address on the Libya situation, he pushed back on some of that criticism.

“Of course, there is no question that Libya — and the world — will be better off with [Moammar] Gadhafi out of power. But broadening our military mission to include regime change would be a mistake,” said Obama in Monday’s address.
