Ready for Hillary, the super PAC devoted to encouraging Hillary Clinton to run for president in 2016, raised $1.25 million in the first half of 2013, including $1 million in June, according to a super PAC official.

The news was first reported by the New York Times's Nicholas Confessore.

The PAC only files twice per year -- the rules say PACs that filed quarterly in 2012 file semi-annually in 2013.

Ready for Hillary says it will not accept million-dollar donations, as some super PACs have, instead opting for more of a grassroots approach to wooing Clinton into the race. The maximum donation it accepts is $25,000.
