The Senate Conservatives Fund and its affiliated super-PAC raised about $9.3 million last year, a landmark in a non-election year for the group, its leader told The Hill.

From July to December, the super-PAC originally founded by then-Sen. Jim DeMint (R-S.C.) to support the election of non-establishment Republicans, only took in about $317,250, according to newly released federal election forms.

It ended the year with nearly $5.6 million in cash on hand, after spending more than a half-million dollars on independent expenditures, including a large media buy opposing Senate Majority Leader Mitch McConnellAddison (Mitch) Mitchell McConnellGOP senator blocking Trump's Intel nominee Spending bill delay raises risk of partial government shutdown support GOP leaders to Trump: Leave Mueller alone MORE (R-Ky.).

From January to June, the super-PAC took in more than $1.3 million, propelled by a $1 million check from notable Republican donor and businessman, the late Bob Perry. 

However, most of the organizations’ fundraising is done through its traditional political action committee, the Senate Conservatives Fund – which took in about $738,645 during the month of December alone, according to its executive director, Matt Hoskins. The official form is not yet posted on the Federal Election Commission's website.

The Senate Conservatives Fund closed out the year with nearly $7.6 million in overall contributions -- many of which were less than $200 each -- bringing the total of the two groups to about $9.3 million.

“Thanks to the support of thousands of freedom-loving Americans across the country, we raised $9.3 million last year, which is the most we've ever raised in a non-election year,” wrote Hoskins in an email. “This activism shows how determined the grassroots are to promote conservative policies and elect conservative candidates.”

The Senate Conservatives Fund starts off 2014 with nearly $860,000 in its coffers.
