In the biggest free-agency acquisition of the 2016 Presidential contest, the billionaire investor Paul Singer has acquired Florida senator Marco Rubio for a rumored eight-figure sum, pending a physical. Just hours after the deal was inked, Rubio was flown by private jet to Singers training facility in East Hampton, where the senator will submit to a series of gruelling drills before the deal is finalized. We are making a four-year deal with Marco, with an option for another four, an associate of Singers said. We like what weve seen of him on tape, but we want to be sure that he has what it takes to go the distance. According to those familiar with Singers physical workouts for political candidates, Rubio will submit to a number of demanding tests, in which the billionaire will bark commands and the senator will be measured for his reaction times and accuracy. You have to be in peak condition for these workouts, the associate said. Jeb got totally winded. Arriving at Singers training camp, Rubio said he was excited and honored to be a part of the Singer organization. I talked to a lot of other billionaires, he told reporters. Sheldon Adelson, and the Koch brothers, of course. But at the end of the day Mr. Singers scheme was the best fit. Im looking forward to earning every dollar he paid for me.
