The Adelsons separately donated another $10 million to the pro-Mitt Romney super PAC Restore Our Future in the last weeks of the campaign. Together, the couple donated $30 million to Restore Our Future.
Their donations throughout the campaign have drawn scrutiny, including their contributions to the pro-Newt Gingrich super PAC Winning Our Future. Their January cash infusions were a major reason the former House speaker's campaign stayed alive.
Restore Our Future spent $45.5 million from October 18th through the end of November, according to a FEC report.
In the same period, the group brought in just over $22 million.
With the election over we will now have a more complete picture of the super PACs financial activity in this campaign. During this year Restore Our Future ended up spending $146.4 million and raised $147 million. The group spent almost all of its reserves reporting now having $842,000 cash on hand.
