Two Colorado Democratic state senators facing recalls over their support for new gun restrictions argued Wednesday to stop the proceedings, telling a judge the petitions against them are invalid and that no election should be set until judicial review is complete.

State Senate President John Morse of Colorado Springs and Pueblo Sen. Angela Giron argue the recall petitions against them were improperly worded and didn't ask for an election to appoint a successor.

Denver District Court Judge Robert Hyatt heard arguments Wednesday and will rule Thursday afternoon whether to grant a preliminary injunction.

Supporters of the recall maintain their petitions are valid. The Secretary of State's office has agreed and is seeking a court order to force Democratic Gov. John Hickenlooper to set an election date.
