The Democratic Senatorial Campaign Committee outraised its Republican counterpart in January by $2 million, according to figures released by the committees.
The DSCC announced Wednesday it raised $6.6 million in the first month of the year. The monthly haul brings the committee's cash on hand to $15 million as of Jan. 31. It also paid down its debt to $2.5 million.
The National Republican Senatorial Committee announced Tuesday it raised $4.6 million in January and ended the month with more than $10 million in cash on hand. The NRSC carries no debt.
Senate Democrats are facing a lopsided map and tens of millions in outside spending against their incumbents. The party can lose no more than five seats net to retain control of the Senate in November.
In a statement, DSCC Executive Director Guy Cecil said the party needs "our supporters to continue to step up so that we can provide our campaigns with cover on television and fund the most aggressive field efforts in history.”
