Obama Says Clinton Meant No Offense With RFK Comment

From CBS News' Maria Gavrilovic:

SAN JUAN, P.R. -- This afternoon, Barack Obama responded to Hillary Clinton's comments yesterday when she referenced th assassination of Robert F. Kennedy as a reason she's staying in the race this year. Obama said he believes that Clinton was not trying to be offensive.

"I have learned that when you are campaigning for as many months as Senator Clinton and I have been campaigning, sometimes you get careless in terms of the statements that you make and I think that is what happened here," Obama said in a radio interview today.

"Senator Clinton says that she did not intend any offense by it and I will take her at her word on that."

Meantime, the Puerto Rican community hosted a caminata - a traditional march for government officials - for Obama in Old San Juan. As he marched, salsa music played throughout the town.

"I will never forget the support and the friendship that I've seen here in Puerto Rico and I hope that everybody is going to be turning out to vote next Sunday because you can go ahead and put me over the top. If we do well in Puerto Rico, there is no reason why I will not be announcing that I am the Democratic nominee for President of the United States of America."

There are 55 delegates at stake in what's turned out to be relevant Puerto Rico caucuses on June 1.
