Attorney General Ken Cuccinelli is urging Virginians to contribute to his gubernatorial campaign soon – before a state law prohibits him from accepting donations for at least 30 days.

The presumptive Republican nominee for governor sent an email last weekend to supporters asking for cash to help fight Democrat Terry McAuliffe in what is expected to be an expensive race this fall. But Cuccinelli warned his fans that he can’t take any cash once state lawmakers return to Richmond on Wednesday. State law bars legislators and constitutional officers from accepting campaign contributions while the General Assembly is in session.
