"Thousands of people stepped up and helped us raise over $100,000! The message is clear ... voters should pick candidates, not party bosses," he tweeted.
It's unclear, however, if he met that goal by the deadline he had originally set, midnight on Thursday.
Akin's comments, that pregnancies from "legitimate rape" are rare because "the female body has ways to try to shut that whole thing down," set off a firestorm of outrage nationwide. The backlash culminated in a number of high-profile Republicans, including GOP presidential nominee Mitt Romney, asking Akin to exit the race, and the National Republican Senatorial Campaign and conservative super-PAC Crossroads GPS both pledging to withdraw funds from the race.
But Akin refused to leave, and instead has launched a grassroots fundraising effort based around the idea that he's the anti-establishment candidate bucking the "party bosses."
