Obama to attend Polish president's funeral

President Barack Obama will travel to Poland on Saturday to attend the funeral of the late Polish President Lech Kaczynski and his wife, Maria, who were killed in a plane crash last week.

White House press secretary Robert Gibbs announced the trip Tuesday from the nuclear security summit, at which Obama had asked the more than 40 world leaders gathered to stand for a moment of silence earlier in the day.

Gibbs said Obama will travel to Krakow for the funeral "to express the depth of our condolences to an important and trusted ally, and our support for the Polish people, on behalf of the American people."
