WASHINGTON — Miriam Adelson is a doctor, philanthropist and humanitarian, but is perhaps best known as the wife of Sheldon Adelson, a Las Vegas casino magnate considered one of the nation's most powerful Republican donors. She gets to add a new title Friday when President Donald Trump honors her with the Presidential Medal of Freedom.

Miriam Adelson is among seven people Trump is recognizing with the medal, the highest honor America can give a civilian.

The other recipients include retiring Republican Sen. Orrin Hatch of Utah, one of the longest-serving senators in U.S. history; Alan Page, who was elected to the Minnesota Supreme Court after an NFL career with the Minnesota Vikings and Chicago Bears; and Roger Staubach, the Hall of Fame Dallas Cowboys quarterback.

Posthumous honors are being granted to Elvis Presley, Babe Ruth and Antonin Scalia, the conservative Supreme Court justice.

The Adelsons gave Trump's presidential campaign a $30 million boost in the final months of the 2016 race. The couple followed up this election cycle by donating $100 million to the Republican Party for last week's midterms.

Miriam Adelson, 73, is an Israeli-born, naturalized U.S. citizen who earned a medical degree from Tel Aviv University and founded a pair of drug abuse treatment and research centers in Las Vegas and Tel Aviv. She and her husband own the Las Vegas Review-Journal and Israel Hayom newspapers.

The Adelsons are also avid supporters of Israel. Their passion for strengthening the country, along with Israel-U.S. relations, has helped keep such policy priorities as relocating the U.S. embassy from Tel Aviv to Jerusalem front and center in the Republican Party and the Trump administration.

Trump moved the embassy in May, and Sheldon Adelson, who had offered to personally fund the move, was seated in the front row for the ceremony.

Robert Weissman, president of public interest group Public Citizen, said it was difficult to believe the decision to recognize Miriam Adelson was based on merit.

"It's emblematic of the corrupt and transactional presidency of Donald Trump, and it is a shame, but not a surprise, that he is corroding and corrupting a civic treasure, an honor like the Medal of Freedom," Weissman said.

Lindsay Walters, a White House spokeswoman, said Trump used the process that previous administrations have followed to settle on his group of honorees. The process was coordinated by the office of the staff secretary, taking into account recommendations from the public, relevant presidential advisory bodies, the Cabinet and senior White House staff, she said.

The award is given to individuals "who have made especially meritorious contributions to the security or national interests of the United States, to world peace, or to cultural or other significant public or private endeavors."

Miriam Adelson said she is "deeply humbled and moved by this exceptional honor."

"Liberty is at the heart of my decades of work against substance abuse. Drug dependency is enslavement, for the user and his or her family and society, and treatment an emancipation," she said in a statement released Thursday by Las Vegas Sands Corp., a company owned by Sheldon Adelson that operates hotels and casinos around the world. "Together, my husband, Sheldon, and I have dedicated our lives to freedom: to a free market that benefits the greater good and to philanthropic endeavors that succor those suffering from poverty and disease."

E. Fletcher McClellan, a political science professor at Elizabethtown College in Pennsylvania, said there are no limitations on who can receive the presidential honor.

"He has total discretion as to who and when and how," said McClellan, who has studied the Presidential Medal of Freedom.

Christopher Devine, a politics professor at the University of Dayton, questioned Miriam Adelson's impact on American culture or national interests as compared to past recipients like Oprah Winfrey or Bruce Springsteen. Both Winfrey and Springsteen received medals from President Barack Obama, whom they supported politically.

"This is what leaves many people wondering whether President Trump singled her out for an award as something of a thank-you for her and husband Sheldon Adelson's very substantial donations to Republican candidates and causes over the years, including ones in support of Trump's election in 2016," said Devine, who wrote a book about the Presidential Medal of Freedom.

Devine said that while Miriam Adelson isn't the first campaign contributor to receive a Presidential Medal of Freedom, the size of her campaign contributions sets her apart from the rest.
