A surprising twist in fate, Marco Rubio went from a painful presidential rival to President Donald Trump's go-to guy.

At the beginning of the new administration, current and former officials speculated that Rubio would be one of the first cabinet officials to show, as his first American certificate was questioned because of his previous foreign policy perspective.

Instead, Rubio just continues to favor the president - so much that he now plays four different roles in the administration than ever before.

"I called Marco when I had a problem. He got it fixed," Trump quipped earlier this month.

First, Rubio confirmed his entry into the state position with a 99-0 Senate. Trump and his team then demolished the U.S. Agency for International Development and merged at Rubio's State Department leadership, naming it as acting director. The secretary then led the National Archives with his acting ability, and as of last week, he also replaced Mike Waltz as acting national security consultant.

“It’s an expression of trust,” said Andrew Taber, a former senior official with the State and National Security Council (NSC). "This shows that the president still likes Secretary Rubio, despite the high odds."

Trump believes that the interim arrangement can last up to six months, and while this may express the president's confidence in Rubio, some question whether a person can effectively juggle four high-profile roles.

"Marco Rubio is talented, but no one can do it," said Joel Rubin, a former senior State Department official.

Henry Kissinger was the last person to serve as Secretary of State and National Security Advisor, holding a role for more than two years from 1975 to 1977. But that was half a century ago, and the threat faced by the state was only multiplied by.

Rubin, who serves both the Democratic and Republican administrations, said the workload is “unfair to individuals, unfair to taxpayers, unfair to President Trump, who needs strong, independent advice from national security advisers.”

"The president has formed a very talented team that is entirely committed to putting the United States and Americans first," a senior State Department official said in an investigation in response to many of Rubio's responsibilities. "Secretary Rubio looks forward to his interim national security adviser while ensuring that the State Department's mission-critical work continues uninterrupted."

Traditionally, the National Security Advisor was the president’s closest aide in war, peace and global crisis – Physics is located near the Oval Office, ready to introduce the president at any time. This proximity is difficult to maintain when the same person is flying diplomatic missions overseas.

“If he had to fly to Pakistan to stop the nuclear war, then the president’s national security adviser (usually sitting next to him) was not there.”

The reshuffle was a broader reorganization within the National Security Council, which lost waltz in early April, deputy adviser Alex Wong and many staff members. Several sources say that such sparse personnel only complicates the bets.

"There are major national security issues in three different theaters, Europe, the Middle East and Asia. A hot war, one is a half battle, it does become tense in Asia," a former NSC official said. "The president's national security team needs to be filled in, and many people in the state and the Ministry of Defense still need to be confirmed."

National Security Advisors “is one of the president’s closest relationships,” said Michael Allen, president and senior director of the NSC. "National security advisers must always be close to the president. Or at least be able to introduce the president all the time. So that's more of a duty for Rubio, and they've abandoned it."

Still, Allen said the president’s personal comfort to his supreme national security aide could outweigh structural issues.

"If the president feels he needs Rubio there, then it's a good solution," Allen said. "At least in the short to medium term."

Others say Rubio's promotion may be more symbolic than operation, especially in the White House where influence does not always match the job champion.

“I don’t think so, ‘Can Marco Rubio do four jobs?’ Yes, “Did he allow him to do one job – is this the Secretary of State? "The foreign peers may think he was pleasant at the meeting, but they don't necessarily believe he can deliver it. ”

Feierstein noted the rise of informal advisers such as the United States Agency for International Development (USAID), Stephen Miller and the spread of envoys like Steve Witkoff, who bypassed Rubio entirely. "You have a lot of people who report directly to Trump or someone else. So now it's just chaos," he said.

Even Rubio's ideological positioning raises questions. Rubio was a staunch foreign policy Hawks during his Senate tenure, presided over foreign policy agencies in recent months, including propaganda to Russia and dramatic State Department budget cuts – moves he may have opposed.

"He decided to accommodate," Feestein said.

But Rubio has the ability to meet with the voters they are in - and act as a happy warrior to the president - which may be the key to his longevity. Related to voices such as National Intelligence Director Tulsi Gabbard and Vice President of Foreign Policy, JD Vance, will only cause further headaches for the president.

For him, the table remains optimistic. "Rubio is full of energy and he knows these issues. He has been working on foreign policy for years," he said. "It's a positive signal. But how long a person can do the work - in what circumstances - depends on him."
