Sen. Marco Rubio (R-Fla.) is emerging as casino magnate Sheldon Adelson's preferred candidate in the 2016 GOP primary, according to Politico's Alex Isenstadt.

The 81-year-old Adelson — the world's 18th-richest person and aspiring GOP kingmaker — considers Rubio the "future of the Republican Party" and admires his hawkish stance on Israel. The two have a fairly chummy relationship, too.

Rubio has reached out to Adelson more often than any other 2016 candidate, sources close to Adelson say, and has provided him with the most detailed plan for how he’d manage America’s foreign policy.

Since entering the Senate in 2011, Rubio has met privately with the mogul on a half-dozen occasions. In recent months, he‘s been calling Adelson about once every two weeks, providing him with meticulous updates on his nascent campaign. During a recent trip to New York City, Rubio took time out of his busy schedule to speak by phone with the megadonor. [Politico]

Adelson spent roughly $100 million on the 2012 election, much of that to prop up the floundering candidacy of former House Speaker Newt Gingrich. That's not quite the $300 million the Koch brothers are prepared to drop on the 2016 elections, but it's a pretty healthy start. A handful of Republican White House hopefuls plan to meet with Adelson this weekend in Las Vegas. Jon Terbush

People love a good mystery, and President Trump's personal lawyer, Rudy Giuliani, provided the public with an Italian restaurant-themed enigma that remains unsolved.

Giuliani told his Twitter followers late on Friday night to check out a Yelp review for a restaurant called Mama Lisa. There was just one problem — the former mayor of New York forgot to include a link, leaving everyone in the dark.

Giuliani didn't seem to notice his mistake, however, sending an unrelated tweet shortly after. But the fact that it slipped Giuliani's mind doesn't mean others missed it. This is the internet, after all, which means several people hopped right on it, relishing the opportunity to try out some of their best political humor.

It remains to be seen which review, exactly, Giuliani was referring to, but — for what it's worth — customers generally seem to agree with him about the high quality of Mama Lisa's food and service. Tim O'Donnell

Maine became the fourth state — joining California, Mississippi, and West Virginia — to end most non-medical exemptions for mandatory childhood vaccines, The Hill reports.

The state's governor, Janet Mills (D), signed the bill, which eliminates religious and philosophical exemptions and will go into effect 90 days after the state legislature adjourns. Now, only doctors and pediatric primary care givers can determine if there is need for a medical exemption.

Maine reportedly has one of the highest rates of non-medical vaccine exemptions in the country. Last year, The Hill writes, the kindergarten vaccination opt-out rate was 5.6 percent, more than three times the national average. But with a confirmed case of measles in the state, it appears Maine's government was not taking any chances. "It has become clear that we must act to ensure the health of our communities," state Rep. Ryan Tipping (D) said.

Still, there are opponents to the new bill, who emphasize religious freedom. "We are pushing religious people out of our great state," state Sen. Lisa Keim (R) said earlier this month. "And we will be closing the door on religious people who may consider making Maine their home. We are fooling ourselves if we don't believe an exodus would come about." Tim O'Donnell

Intelligence officials are concerned about the new authority Attorney General William Barr holds concerning classified information, The Washington Post reports.

On Thursday, by way of executive order, President Trump granted Barr the power to reveal government secrets during the attorney general's review of what the White House calls "surveillance activities during the 2016 election." Trump has long maintained that the U.S. government was spying on his campaign in an attempt to undermine the election process.

It is reportedly unprecedented for an official who does not head an intelligence agency to have the ability to disclose such information, which has some people worried that Barr could selectively declassify information, distorting the roles of the FBI and CIA during their investigations into 2016 Russian election interference. Others are concerned that Barr could compromise sources "deep inside the Russian government."

The Post reports that Trump's decision stems from his greater sense of trust in Barr than in Director of National Intelligence Daniel Coats. "This is a complete slap in the face to the director of national intelligence," James Baker, the former FBI general counsel, said. Michael Morell, a former CIA deputy director, described the situation as "another destruction of norms that weakens our intelligence community." Read more at The Washington Post. Tim O'Donnell

President Trump has tapped Ken Cuccinelli as the new director of U.S. Citizenship and Immigration Services.

While Cuccinelli's hiring was reported as early as Tuesday, it remained unclear what exactly Cuccinelli's role in the Department of Homeland Security would be. He'll replace the agency's current director, L. Francis Cissna, whom The Washington Post describes as having "deep expertise" when it comes to immigration law, but was forced out following criticism from Trump senior policy adviser, Stephen Miller.

Cuccinelli is considered an immigration hardliner and is known for his "combative" television appearances and enthusiastic support for Trump's immigration proposals. He has, however, drawn ire from both Republicans and Democrats. Sen. Mitch McConnell (R-Ky.) has reportedly vowed to block Cuccinelli from getting confirmed for any position. McConnell reportedly blames Cuccinelli for promoting insurgent candidates running against sitting Republicans during the 2014 midterm elections. Tim O'Donnell

Some of the momentum gathered by states seeking to implement more restrictive abortion measures in recent weeks was halted when a federal judge on Friday issued a preliminary injunction, blocking a Mississippi law that bans abortion after the detection of a fetal heartbeat.

Attorneys for the state's only abortion clinic said the law would effectively make all abortions illegal because most women are not yet aware of their pregnancy when a fetal heartbeat is first discovered. The bill makes an exception when the mother's health is at risk. The law, which is one in a series of Republican-sponsored abortion bills across the United States, was scheduled to take effect in July.

The judge, Carlton Reeves, wrote that a woman's free choice "outweighs any interest the state might have in banning abortions after the detection of a fetal heartbeat." Reeves also blocked a 2018 Mississippi law that would have banned abortion at 15 weeks. The state is still appealing that decision. Reeves added that the fact Mississippi lawmakers passed another ban after the first was struck down "smacks of defiance to this court." Tim O'Donnell

As anticipated, President Trump on Friday declared a national emergency in response to rising tensions between the United States and Iran, allowing him to complete the sale of over $8 billion worth of weapons to Iran's regional rival, Saudi Arabia, as well as the United Arab Emirates and Jordan, all despite congressional objections.

Congress had blocked the sale of offensive weaponry to Saudi Arabia and the UAE for months as a result of those countries' air campaigns in Yemen and other human rights abuses. But Trump used a loophole to circumvent Congress and go ahead with the sale.

The emergency declaration was met with bipartisan disapproval. Sen. Chris Murphy (D-Conn.), said there is no new emergency reason to supply Saudi Arabia with arms and "doing so only perpetuates the humanitarian crisis" in Yemen. Rep. Mike McCaul (R-Texas) called the decision "unfortunate" and said he would have preferred the Trump administration "utilize the long-established and codified arms sale review process."

Secretary of State Mike Pompeo said the sales were necessary to deter Iran, but that the decision to side step Congress was a "one-time event." Tim O'Donnell
