New York Sen. Charles E. Schumer’s campaign committee gave money to eight Senate candidates who could help Democrats win back majority control of the chamber in November, according to Federal Election Commission reports.

Schumer’s campaign contributed $500,000 each to Democrats in competitive Senate races in Indiana, New Hampshire, Pennsylvania and Nevada, the (Rochester) Democrat and Chronicle reported. The Rothenberg & Gonzales Political Report/Roll Call rates all four contests as Tossups.

The New York senator also gave $250,000 to Senate candidates Missouri Secretary of State Jason Kander and former state Rep. Deborah Ross in North Carolina. The race in Missouri is rated a Tossup while the North Carolina race is Tilts Republican.

Illinois candidate Rep. Tammy Duckworth and former Sen. Russ Feingold, who is seeking his old seat in Wisconsin, received $100,000 in donations. Both of these races are rated as Leans Democratic.

Donations of $50,000 each went to Senate candidates in Ohio, California and Colorado. Ohio is rated as Republican Favored, but California and Colorado are both Safe Democrat races. 

The Schumer campaign did not comment on why certain tight races received more money than others but if Democrats win the Senate majority, Schumer is in line to become the chamber’s majority leader. 

Democrats need to net five seats to win control of the Senate, or four seats and a win by Hillary Clinton in the presidential race, in which case her vice president would break a tie. Should Clinton win, her running mate Virginia Sen. Tim Kaine would resign his Senate seat, and the state’s Democratic Gov. Terry McAuliffe would appoint his successor. 

Schumer’s campaign committee ended September with $20.5 million in the bank. He gave $3 million to the Democratic Senatorial Campaign Committee between July 1 through Sept. 30, as well.

His committee spent 7.69 million but only $1.49 million went to Schumer’s safe re-election race. Roughly $6.19 million was donated to other campaigns and a few charities.
