Is Obama about to break the law?

Washington (CNN) - President Obama may be on the brink of breaking the law.

At issue: The 1973 War Powers Act, which says if the president does not get congressional authorization 60 days after military action, the mission must stop within 30 days.

The president formally notified Congress about the mission in Libya with a letter on March 21, which makes Friday the 60-day deadline.

Administration officials don't yet feel compelled to seek such permission and some party leaders have been satisfied with the information flow so far, but still, inaction is angering other lawmakers from both the left and the right who rarely agree on anything.

Rep. Brad Sherman, D-California, tells CNN he believes Obama is trying to "bring democracy to Libya while shredding the Constitution of the United States."

"He cannot continue what he is doing in Libya without congressional authorization. When a president defiantly violates the law, that really undercuts our efforts to urge other countries to have the rule of law," Sherman said.

Sen. Rand Paul, R-Kentucky, concurs.
