Mitt Romney's team raised nearly $112 million in the first half of October, his spokeswoman Andrea Saul posted Thursday on Twitter.

Romney's monthly cash hauls come from his campaign, the Republican National Committee and fund-raising efforts by state and local parties.

In a separate release, the campaign said nearly 92% of donations received between October 1 and October 17 were $250 or less. And with less than two weeks before Election Day, Romney's team reports having $169 million cash on hand.

The GOP nominee saw a boost in poll numbers this month after a series of strong debate performances. Following the first presidential debate on October 3, his campaign announced they raised $12 million in 48 hours.

The latest numbers do not include fund-raising that occurred around the final presidential debate, which took place Monday, October 22.

A major super PAC supporting Romney's candidacy had a strong night, too, the group's founder said the day after the debate.

"I think that today will probably be the best fund-raising day we've had, if not one of the top two fund-raising days we've ever had," Charlie Spies of Restore our Future said on CNN's Erin Burnett "OutFront."

In September, the Romney effort raised $170 million, while President Barack Obama's team raised $181 million last month.

Romney's campaign announced they held their final fund-raiser for the cycle on Saturday, shifting focus to public rallies in the final two weeks of the race.

Through the end of September, Romney had raised more than $361.3 million this cycle, Federal Election Commission records show.

His running mate, Rep. Paul Ryan, however, continues to attend fund-raisers this week.
