Colorado Democratic Senator Mark Udall and Alaska Republican Senator Lisa Murkowski are once again urging members of Congress to cross the aisle and sit with members of the opposite party during Tuesday鈥檚 State of the Union address.

The senators are Rep. Ron Barber (D-AZ.) and Rep. Matt Salmon (R-AZ.) in calling for bipartisan seating at this year鈥檚 address. More than chose to sit with the opposite party in 2011, when the idea was first proposed by Udall and Murkowski following the shooting of Arizona Congresswoman .

This year however, reports from Washington say the number of participants .

鈥淚t鈥檚 symbolic, but also function will follow form. If you sit together then you鈥檙e more likely to find ways to work together,鈥� Senator Udall said. 鈥淧artisanship has reached new heights. That鈥檚 all the more reason on the State of the Union night to set aside some of those differences鈥�

Prior to 2011, members of Congress would sit with their own parties on opposite sides of the House of Representatives where the President's address takes place.
