President Obama is in Northern Ireland Monday — the first stop on a three-day European visit that includes a G-8 summit meeting and a side trip to Berlin.

The president begins his tour with a speech in Belfast, celebrating Northern Ireland's peace process and urging young people in the country to keep it moving forward.

President Obama on Thursday unveiled a major pivot in White House counterterrorism policy, calling for a limiting of CIA drones strikes and for a renewed effort to close the U.S. detention center at Guantanamo Bay, Cuba.

Speaking at the National Defense University in Washington, D.C., the president said the death of Osama bin Laden and most of his top lieutenants, and the fact that there have been no large-scale terrorist attacks on the U.S. homeland, meant that a new policy was in order — one that concentrates on capturing, rather than killing terrorist suspects.

Organizing for Action — a group that formed out of President Obama's re-election campaign — has posted five tweets in the past week about climate change using the @BarackObama Twitter account.

Former CIA Director David Petraeus is under renewed scrutiny over the role he played in creating the discredited "talking points" about the attack that killed four Americans last year in Benghazi, Libya. The Washington Post has a front-page story Wednesday that suggests Petraeus sought to shape the resulting memo to favor his agency.
