Politico reported in 2021 that billionaire casino magnate and "Republican kingmaker" Sheldon Adelson passed away at the age of 87.

While Adelson was a noted supporter of former President Donald Trump, his widow has stayed neutral in the GOP primary race. However, the fact that Trump recently came calling suggests that her stance may soon change. 

Mrs. Adelson and her late husband gave $90 in 2020 to a pro-Trump super PAC

According to Politico, the former president traveled to Las Vegas and had dinner with Miriam Adelson this past Thursday.

While a representative for Mrs. Adelson did not respond to Politico's request for comment, the website pointed to a pair of unnamed sources said to be familiar with the matter.

Politico also pointed out that Mrs. Adelson and her late husband were the former president's biggest financial backers in his 2020 White House race, contributing some $90 million to a pro-Trump super PAC.

This is not Trump's first meeting with Mrs. Alderson, as Politico reported that the two had dinner together this past October.

Dinner part of larger strategy to court high-dollar donors

The meal took place after Trump delivered remarks at the Republican Jewish Coalition's annual convention in Las Vegas.

Yet Politico pointed out that Mrs. Alderson also had dinner around the same time with former United Nations Ambassador Nikki Haley, who is challenging Trump for the Republican Party's presidential nomination.

Trump's outreach to Mrs. Alderson is apparently part of a larger strategy to court high-dollar donors, another example of which came last month.

Politico reported last month that the former president attended an event at the Florida home of billionaire investor John Paulson along with "more than two dozen of the party’s biggest check-writers."

Former DeSantis donor attended meeting with Trump

The website also pointed to a meeting Trump had with hotel executive Don Ahern as well as casino billionaires Frank and Lorenzo Fertitta.

Also in attendance was Robert Bigelow, an aerospace tycoon who had previously been Florida Republican Gov. Ron DeSantis' biggest backer.

What's more, Politico observed that Trump appears to have won over Texas oil billionaire Tim Dunn, who contributed $5 million to the pro-Trump super PAC MAGA Inc despite having supported the Club for Growth, an organization which once opposed Trump.

Trump's efforts to befriend wealthy figures is something of a new approach for Trump, as Politico recalled how he "has not always enjoyed a warm relationship with the party's well-heeled donor set."
