President Barack Obama is cancelling more campaign events to monitor Hurricane Sandy back in Washington.

The latest political event to get scrapped as the storm heads to the East Coast is the president's trip to Green Bay, Wis., Tuesday.

The White House announced Obama was canceling that trip as Air Force One was en route to Washington from Florida Monday morning. The president decided not to attend a noon rally in Orlando Monday so that Air Force One could get safely back to Washington.

With the massive East Coast storm playing havoc with people's work and school at the beginning of the new week, Obama press secretary Jay Carney says the president is returning to the capital today to, quote, "monitor the preparations for and early response" to the hurricane.

Four critical election states are affected by the storm -- North Carolina, Virginia, Ohio and New Hampshire.
