The National Republican Congressional Committee raised $4.5 million in January, a sizable increase from December when the committee took in $3.2 million.
As it prepares for the midterm elections, the House GOP political arm has $4.1 million in the bank, said NRCC Chairman Pete Sessions, a congressman from Texas.
The House Republican counterpart, the Democratic Congressional Campaign Committee, has not yet released its January fundraising total. But as of last month, the DCCC had $17 million cash-on-hand.
