The National Republican Congressional Committee raised $5.1 million in April, the committee's best off-year April in the past decade.
In March, the NRCC brought in $8.1 million towards its efforts to retain control of the House, and over the first three months of the year, raised $17.5 million overall.
That marks a slower fundraising pace than the committee's Democratic counterpart, which raised $22.6 million in the first quarter of the year, with $10.2 million in March alone.
Democrats have been bullish on their hopes of taking back control of the House, with Democratic Congressional Campaign Committee Chairman Steve Israel (D-N.Y.) asserting in March that committee is "doing everything we can to put [the House] in play" in 2014.
Democratic prospects are far from favorable, however, as they'll have to net 17 seats, and many of their targets are in districts that Republican Mitt Romney won in 2012.
