(NBC) - We're expecting more reaction and debate today over stand your ground laws in states across the country.  Demonstrators spurred by the George Zimmerman verdict spent the weekend calling for the repeal of the state law, and justice for Trayvon Martin.

Today, the conversation will continue, as the President and his former rival are finding common ground on the stand your ground law.

Now President Barack Obama and Republican Senator John McCain agree. The stand your ground law deserves another look. "Stand your ground law may be something that needs to be reviewed by the Florida legislature or any other legislature that has passed such legislation," said Senator John McCain, (R) Arizona.

At least 22 states have had a similar law on the books for years, but the push to repeal them is new, starting just after George Zimmerman was found "not-guilty" in the death of Trayvon Martin.

This weekend saw rallies in more than 100 U.S. cities, including Raleigh, Houston, New York. Protesters are pushing for a change, and "federal" civil rights charges against Zimmerman.

Some fear the law, as it stands, encourages violence and is racially biased. "And so if we start to do some things from the congressional perspective, maybe they can help," said Rep. Marcia Fudge, (D) Ohio.

Friday the President urged lawmakers to take another look at the law, asking if Trayvon Martin was of age and armed, could he have legally shot George Zimmerman. "And if the answer to that question is at least ambiguous, then it seems to me that we might want to examine those kinds of laws," said President Barack Obama

But some say the jury's verdict in this case is unlikely to spur change.

That includes Florida Governor Rick Scott. He agrees with an investigative task force, put together after the shooting. "And they concluded that we didn't need to make a change to the law, and I agree with their conclusion," Governor Rick Scott, (R) Florida.
