“The outpouring of support Sherrod received from Ohioans this quarter will help us continue building grassroots momentum for Sherrod as we discuss his work to save the Ohio auto industry and its 850,000 industry related jobs, fight Chinese currency manipulation, and protect Social Security and Medicare for seniors,” Brown spokesperson Sadie Weiner said in a statement. 

“Despite $10.6 million dollars in special interest cash levying more false attacks on Sherrod than any other Senate candidate in the country, Ohio’s middle class knows they have a champion in Sherrod BrownSherrod Campbell BrownSenate Dems to Mnuchin: Don't index capital gains to inflation Trump on collision course with Congress on ZTE Pa. health secretary: 'Sustainable funding' needed to attack opioid crisis MORE who is fighting every day to create jobs and move Ohio’s economy forward.”

Tester, facing a tougher challenge in Montana against Rep. Denny Rehberg (R-Mont.), said Thursday he had $3.6 million cash on hand. A Rasmussen poll released in June showed the Republican challenger with an edge, 49 percent to 47.

This grassroots campaign continues to gain momentum because Montanans know Jon is up against secretive, out-of-state special interests that are spending millions to buy votes for Congressman Dennis Rehberg,” Tester campaign manager Preston Elliott said in a statement.  “Montanans support Jon because they know he’s an honest Montana farmer who makes responsible decisions, holds himself accountable, and defends our freedoms.”

Candidates are required to file their campaign finance reports for the second quarter to the Federal Election Commission by July 15.
