The St. Petersburg Times reports Marco Rubio's campaign breaks a quarterly fundraising record:

Marco Rubio raised more than $4.5 million in the second quarter, his campaign said, beating rival Charlie Crist's previous record. Crist raised $4.3 million in his first fundraising quarter of the race, back when he was a Republican, a national record for the cycle.

At the end of March, a month before Crist announced he would run as an independent, Rubio had $4 million and Crist had $7 million in the bank. It will be interesting to see how ditching the GOP has affected Crist's ability to raise money.
