President Obama said Sunday he's "outraged" at the murder of late-term abortion provider George Tiller today in Kansas.

"I am shocked and outraged by the murder of Dr. George Tiller as he attended church services this morning," Obama, a backer of abortion rights said in a statement. "However profound our differences as Americans over difficult issues such as abortion, they cannot be resolved by heinous acts of violence."

Tiller was killed earlier today while attending church. A supect is reportedly in custody.

The murder has sparked an online debate about the killings.
