Afghan President Hamid Karzai said Tuesday he backs Gen. Stanley McChrystal, the commander of the allied forces in his country, after Rolling Stone published his criticism of the Obama administration. 

Reuters reported that Karzai's spokesman said: "The president strongly supports General McChrystal and his strategy in Afghanistan and believes he is the best commander the United States has sent to Afghanistan over the last nine years."

McChrystal has since apologized for the article, but a reportedly angry President Barack Obama has summoned him to Washington.

The Rolling Stone article quoted McChrystal as saying he felt betrayed by U.S. Ambassador to Afghanistan Karl Eikenberry, and members of his staff voiced criticism of Obama, Vice President Joe Biden and other officials. 

The incident comes at a time when some in Congress are questioning the U.S. counterinsurgency strategy in the country that McChrystal oversees. 

Karzai has had a sometimes shaky relationship with the White House: Officials recently smoothed over tensions after he slammed Western nations and the United Nations for electoral fraud in the country's presidential elections.
