You might be referring to his "I stand with muslims" statement.
It is often capsulized as:
"I will stand with the Muslims should the political winds shift in an ugly direction."
Below is the original complete quote.
Notice how he follows his usual semantic trick of throwing things back on the "Bad Old USA".
He sets the straw man up, then knocks it down to rationalize his pro-muslim stance.
Good Barack must make things right because the USA does bad things.
Quote from Obama's book "The Audacity of Hope":
"Of course, not all my conversations in immigrant communities follow this easy pattern. In the wake of 9/11, my meetings with Arab and Pakistani Americans, for example, have a more urgent quality, for the stories of detentions and FBI questioning and hard stares from neighbors have shaken their sense of security and belonging. They have been reminded that the history of immigration in this country has a dark underbelly; they need specific assurances that their citizenship really means something, that America has learned the right lessons from the Japanese internments during World War II, and that I will stand with them should the political winds shift in an ugly direction."
