WSJ:

Billionaire casino owner Sheldon Adelson is looking to set up a super PAC to support Donald Trump’s presidential campaign, a move that would add financial firepower from one of the most prolific donors of the 2012 cycle.

Creation of the super PAC, which also would support Republicans in key congressional races, hasn’t been finalized, according to two people familiar with the talks. But it marks the latest sign that more of the party establishment is coalescing around the New York businessman after a bitter primary fight. Mr. Adelson endorsed Mr. Trump in early May, saying the election of another Democrat in 2016 would be “frightening.”

Mr. Adelson, chairman and chief executive ofLas Vegas Sands Corp., is aiming to ensure that his funds be used effectively after his experience in 2012, one of the people said. In that cycle, he spent close to $100 million on Republican causes, supporting one winning and eight losing candidates—including former House Speaker Newt Gingrich and eventual GOP nominee Mitt Romney.
