WASHINGTON (AP) — Senate Democrats’ campaign arm is borrowing $10 million for a last-minute boost to their fundraising as officials see their majority increasingly in peril.

The Democratic Senatorial Campaign Committee on Friday said it also received $1.5 million from the Democratic National Committee and $6.5 million from donors between Oct. 1 and Oct. 15. DNC officials say their transfers to the DSCC will total $5 million by Election Day on Nov. 4.

The National Republican Senatorial Committee said it collected $10.1 million during the first two weeks of October. Of that, $4 million was from the Republican National Committee.

Democrats are trying to fend off Republicans, who could capture the majority for the first time since 2006’s elections if they can net six Senate seats.
