WASHINGTON (AP) — Senate Republicans’ campaign arm raised more than $6 million last month and spent more than twice that in an effort to claim the majority.

The National Republican Senatorial Committee on Friday said it spent about $13 million in August and still has more than $19 million saved.

Party committees typically spend heavily in August and September to buy ads ahead of November’s elections.

The group’s Democratic rival says its fundraising reports for August are not yet completed. Party-run campaign committees have until Sept. 20 to file reports.

Heading into August, the Democratic Senatorial Campaign Committee had outraised the GOP peer in 17 of the 19 most recent months.

Senate Republicans need to pick up a net of six seats to regain the majority, which they lost in the 2006 elections.
