Florida Sen. Marco Rubio dined with Republican mega-donor Sheldon Adelson at a steakhouse in Washington Monday night, a person with direct knowledge of the meeting told Fox News.
Adelson, a casino mogul, pumped nearly $100 million of his own money into super PACs to help 2012 GOP presidential candidate Newt Gingrich and eventual GOP presidential nominee Mitt Romney.
His meeting with Rubio comes as the Florida Republican weighs his own White House bid for 2016.
Rubio donors are aware of the uphill battle in competing against former Florida Gov. Jeb Bush's fundraising machine, especially with a wealthy donor base in Florida that has mostly committed to Bush.
However, Rubio has made an aggressive effort to stay in the game and remain in the top tier of potential candidates as he prepares his 2016 decision.
Rubio donors sources also have confirmed there is a $50 million fundraising target before the Iowa caucuses.
PAC aides are aggressively courting Romney's former finance chairman, Spencer Zwick, who is perceived as a gatekeeper to Romney's formidable donor network. However, many of these former Romney backers are now supporting Bush.
Rubio sources said Monday he could make up his mind as early as April on a 2016 presidential run.
