Secretary of State Marco Rubio has yet another hat to wear and new title under his belt.

President Donald Trump announced the United States’ intention to bid for the World Expo 2035 event in a post on social media.

"The great state of Florida has expressed strong interest in hosting the Expo in Miami, which I fully support," said Trump in a Truth Social post. "Miami Expo 2035 can be the next big milestone in our new Golden Age of America."

Trump appointed Rubio to chair the coordinating efforts and "advance this exciting opportunity," according to the post made on Thursday, Jan. 22.

"I am appointing Miami native Secretary of State Marco Rubio to [c]hair the efforts of coordinating and advancing this exciting opportunity to convene the world," wrote Trump in the post.

The World Expos, known as International Registered Exhibitions, are a gathering of nations intended to, "[find] solutions to pressing challenges of our time," according to the Bureau International des Expositions (BIE).

The event offers "engaging and immersive activities" under one universal theme, according to the organization’s website.

Trump also touted the opportunity would create more jobs in the country and stimulate economic growth.

"In my [f]irst [t]erm as President, I fought hard to bring the 2026 FIFA World Cup and 2028 LA Summer Olympics to the [U.S.]," Trump continued. "I now have the [h]onor of hosting as the 47th President, plus America250, G20 Doral and the G7."

The most recent World Expo event took place in Osaka Kansai, Japan in 2025. The event, which was held from April 13 to Oct. 13, welcomed more than 29 million visitors, according to BIE.

The theme was "Designing Future Society for Our Lives," and provided the opportunity for attendees to come together in a physical place to explore the theme of "life," according to the information page. This was the first post-pandemic World Expo event.

The next World Expo event will be held in Riyadh, Saudi Arabia in 2030, under the theme "Foresight For Tomorrow," according to the organization’s information page.

"In keeping with this global commitment, Expo 2030 Riyadh will be an Expo built by the world, for the world," said a statement on the event page. "It will open opportunities for countries and companies to create a meaningful Expo together, ensuring that the benefits of Expo 2030 Riyadh are shared widely."

The expo will explore the sub-themes of transformational technology, sustainable solutions and prosperous people.

Egypt has shown "strong interest" in also hosting the 2035 event, according to reports, citing "new administrative capital" and the country’s growth. After losing the bid to host the 2030 event, South Korea floated the idea of exploring a 2035 bid.

"I will speak with the central government and Busan residents to review whether we should bid for the World Expo in 2035," Busan Mayor Park Heong-joon said in 2023. "Busan will continue to take on the challenge to create a better future for humanity."

Fox News reached out to the Department of State and the White House and have not received comment at the time of publication.

Former special counsel prosecutor Jack Smith vigorously defended the decisions he made in investigating President Donald Trump after his first term in office, telling members of the House Judiciary Committee on Thursday that his team of prosecutors had uncovered "proof beyond a reasonable doubt" that Trump had engaged in criminal activity.

"Our investigation developed proof beyond a reasonable doubt that President Trump engaged in criminal activity," Smith said. "If asked whether to prosecute a former president based on the same facts today, I would do so— regardless of whether that president was a Republican or a Democrat," Smith said. 

Smith testified publicly for the first time Thursday about the dual special counsel investigation he led looking into Trump's alleged effort to subvert the 2020 election and Trump's alleged retention of certain classified documents. 

JACK SMITH SUBPOENAED FOR DEPOSITION WITH HOUSE JUDICIARY COMMITTEE

Smith brought charges against Trump in both cases, but they were ultimately dropped after Trump's re-election, in keeping with longstanding Justice Department guidance.

Smith resigned shortly after Trump's election to a second term in 2024.

But Smith said Thursday that he had no second thoughts about the actions he took as special counsel, stressing that the decisions that were made with regard to political party and in keeping with longstanding Justice Department policies.

The hearing became acrimonious at times, as House Judiciary Chairman Jim Jordan and other Republicans grilled Smith over certain decisions he made.

One area of focus was his decision to access so-called "tolling records" of certain Republican lawmakers during the probe. Unlike wiretaps, tolling records are phone logs that reveal the phone numbers of incoming and outgoing callers, as well as the time and duration of calls. 

Republicans honed in on this detail Thursday, blasting the actions as "political weaponization." Smith, for his part, defended the tolling records as "common practice" in such investigations.   

Smith previously said that the Public Integrity Section had signed off on the subpoenas, a point corroborated by previously released public records.

Other Republicans assailed Smith's actions as "overly aggressive" and beyond the scope of his authority. 

Rep. Kevin Kiley, R-Calif., meanwhile, blasted Smith for attempting to seek the "maximum litigation advantage at every turn, and "repeatedly circumventing constitutional limitations to the point that you had to be reined in again and again throughout the process."

Trump, in Davos, also weighed in prior to the hearing.

Speaking at the World Economic Forum, Trump said "everybody now knows that" the 2020 election was "rigged," and vowed that "people will soon be prosecuted for what they did." He did not immediately elaborate.

Still, Smith sought to impart on the panel his belief that the special counsel prosecutors had built a strong case against Trump. 

"We observed legal requirements and took actions based on the facts and the law," Smith said, saying the decisions were made "without regard to President Trump's political association."

He also lamented the ousting of FBI agents and Justice Department officials, including members of the special counsel who he said have been fired or unfairly targeted in Trump's first year back in office.

FBI AGENTS SUE TRUMP DOJ TO BLOCK ANY PUBLIC IDENTIFICATION OF EMPLOYEES WHO WORKED ON JAN. 6 INVESTIGATIONS

Trump, he said, "has sought to seek revenge against career prosecutors, FBI agents and support staff simply for having worked on these cases."

"To vilify and seek retribution against these people is wrong," Smith said. "Those dedicated public servants are the best of us, and it has been a privilege to serve with them."

Thousands of FBI personnel in February were forced to fill out a sprawling questionnaire asking employees detailed questions about any role they may have played in the investigation into the Jan. 6, 2021, U.S. Capitol riots — ranging from whether they had testified in any criminal trials to when they last participated in investigation-related activity. 

In the months since, a handful of personnel involved in the Jan. 6 investigations have been abruptly fired as part of an effort that individuals familiar with the action described to Fox News as an act of "retaliation." 

The Justice Department also fired individuals who worked with Smith on the special counsel investigations, as Smith noted Thursday.

"In my opinion, these people are the best of public servants, our country owes them a debt of gratitude, and we are all less safe because many of these experienced and dedicated law enforcement professionals have been fired," he said.
