The National Republican Senatorial Committee, which slightly outraised its Democratic counterpart in April, made a multi-million dollar payment on its debt last month and now carries a burden less than one-third the size of that held by the Democratic Senatorial Campaign Committee.

The NRSC brought in more than $4.2 million in April and ended the month with $5 million in its war chest, according to a committee aide. The group reported a debt of $3.5 million at the end of April, down from $6 million it owed at the end of March.

For its part, the DSCC raised $3.8 million in April and ended the month with $7.6 million on hand — about $2.6 million more than the NRSC has in its coffers — according to a DSCC aide. But the group still carries a large operational debt of $12.6 million, more than $9 million higher than the amounted owed by the GOP’s Senate campaign arm.

The DSCC, which outraised the NRSC by more than $3 million during the first quarter of 2015, had $13.7 million in debt at the end of March.

Meanwhile, the Democratic and Republican House campaign arms each raised around $5 million in April and are now fully debt free.

The National Republican Campaign Committee reported raising $5.1 million last month and has $9.2 million cash on hand. The group completely paid down its $7 million debt in March.
