President Obama on Friday became the first sitting president to address Planned Parenthood's annual meeting, delivering a strongly worded speech defending the embattled organization.

President Obama has been hosting a series of visitors from the Middle East, and all of them have been urging the U.S. to get more involved in Syria.
