Attorneys representing a veteran and two mothers of soldiers are asking a federal court to declare the Iraq war unconstitutional.

They said in court Tuesday that former President George W. Bush overstepped his constitutional authority to invade Iraq in 2003 without Congress officially declaring war.

They say that wasn't the intent of the country's "founding fathers" who wrote the constitution more than 200 years ago.

The government argued that courts do not have authority to rule on a political matter.
