The top super PAC supporting Mitt Romney’s presidential campaign raised just shy of $5 million in May and ended the month with $8.4 million cash on hand.

Restore Our Future’s fundraising report does not include a reported $10 million contribution from casino magnate and former Newt Gingrich supporter Sheldon Adelson, which came to light last week.

The super PAC raised slightly more than it pulled in in April, but it has yet to see a major increase in fundraising now that Romney has secured the GOP nomination. Adelson’s June contribution should help change that.

Top donors to the super PAC last month include Arkansas businessman Warren Stephens and Pennsylvania businessman Rocco Ortenzio, who each gave $500,000; Goldman Sachs managing director Henry Cornell, who chipped in $150,000; three Dayton, Ohio, companies that contributed $333,333 each; Michigan businessman William Keough ($300,000); and a Florida retirement community whose higher-ups combined to give $428,000.

Pittsburgh Tribune-Review publisher Richard Mellon Scaife contributed another $67,500.
