WASHINGTON — Senator Chuck Schumer, the majority leader, plans to transfer $15 million from his campaign account to the Democratic Senate campaign effort as well as to several of the party’s key candidates, according to a Democrat with knowledge of his plans.
The infusion of cash comes as Mr. Schumer appears comfortable in his re-election bid in New York. Now he will redeploy his financial resources in the closing weeks of the midterm campaigns to help him hang on to his job as majority leader.
“Keeping and growing the Democratic majority in the Senate is my top priority,” Mr. Schumer said in a statement.
The Democrat with knowledge of the plans, who insisted on anonymity, said Mr. Schumer would send $5 million directly to the Democratic Senatorial Campaign Committee for its campaign operations. He will also provide $1 million each to Democrats in several races seen as most critical to the party’s chances of holding on to its majority.
The incumbents receiving the money will be Senators Raphael Warnock of Georgia, Mark Kelly of Arizona, Catherine Cortez Masto of Nevada and Maggie Hassan of New Hampshire.
Five other Democratic candidates trying to unseat Republican incumbents or win open seats — Mandela Barnes in Wisconsin, John Fetterman in Pennsylvania, Cheri Beasley in North Carolina, Representative Tim Ryan in Ohio and Representative Val Demings in Florida — will also receive $1 million apiece.
Mr. Schumer will contribute $500,000 each to Senators Michael Bennet of Colorado and Patty Murray of Washington, who face Republican challengers.
The Republican Senate campaign organization has faced money challenges, and individual G.O.P. candidates have been outraised by Democrats mounting strong efforts in what was initially viewed as a difficult political environment likely to cost them the majority.
But legislative successes and the Supreme Court’s decision to overturn Roe v. Wade have put Democrats on the offensive in recent weeks, raising hopes in the party that it can retain Senate control.
As of his last campaign finance report, at the end of June, Mr. Schumer had nearly $38 million in cash on hand for his re-election bid, providing him with a cushion to divert money from his own campaign.
A political action committee tied to Senator Mitch McConnell of Kentucky, the Republican leader, has also invested heavily in Senate races, trying to make up for the financial shortcomings of some Republican campaigns.
