3rd District Republican Congressman Walter Jones has introduced a resolution to Congress that would make it an impeachable offense if the President were to commit military force without approval by Congress.
The current law allows the President to merely give Congress 48 hours notice prior to committing troops to action for 60 days, followed by a 30 day withdrawal period. For any longer engagement, the President requires Congressional approval.
Jones' Resolution seems designed solely for the purpose of preventing the President from using force against the terror-supporting regime of Syria's Bashar al Assad. The maneuver is unlikely to get much support from either Democrats or his fellow Republicans, other than isolationist extremist Ron Paul.
