(CNN) -

The National Republican Campaign Committee, which is tasked with electing party members to the House of Representatives, outraised their Democratic competitors in April by a small margin, according to figures released Friday.

The NRCC raised $6.9 million in April, and increased their war chest by more than $4 million. The group ended the month with $31.3 million in the bank.

The group said at this point in the 2012 election cycle, they're nearly $20 million richer than they were in 2010.

Their counterparts, the Democratic Congressional Campaign Committee, said they had their best April in history, raising $6.48 million and ending with $25 million cash on hand. The Democrats also said they had no campaign debt.

Democrats would need to capture 25 seats currently held by Republicans in November to win back control of the lower chamber.
