Washington: President Donald Trump’s motorcade took a different route than usual to the airport as he was departing Florida on Sunday due to a “suspicious object,” according to the White House.

The object, which the White House did not describe, was discovered during security sweeps in advance of Trump’s arrival at Palm Beach International Airport.

“A further investigation was warranted, and the presidential motorcade route was adjusted accordingly,” White House press secretary Karoline Leavitt said in a statement Sunday.

The president, when asked about the package by reporters, said, “I know nothing about it.”

Trump left his Palm Beach, Florida, club, Mar-a-Lago, around 6:20 p.m. for the roughly 10-minute drive to the airport, but took a circular route around the city to get there.

During the drive, police officers on motorcycles created a moving blockade for the motorcade, at one point almost colliding with the vans that accompanied Trump.

Air Force One was parked on the opposite side of the airport from where it is usually located and the lights outside the plane were turned off.

Anthony Guglielmi, the spokesman for U.S. Secret Service, said the secondary route was taken just as a precaution and that “that is standard protocol.”

In a separate development, Trump on Sunday (local time) said that Washington may be forced to take action against Iran amid ongoing nationwide protests, even as he revealed that Tehran has reached out to Washington seeking negotiations.

Speaking to reporters onboard Air Force One, Trump said Iranian leaders had contacted Washington to discuss diplomatic engagement.

When asked whether Iran wanted to engage in diplomatic talks with him, Trump responded affirmatively.

"They do. They called. Iran called to negotiate yesterday. The leaders of Iran called. They want to negotiate. I think they're tired of being beat up by the United States. Iran wants to negotiate," Trump said.

The US President, during the interaction, further added that a meeting was in the process of being arranged but cautioned that developments on the ground inside Iran could force Washington's hand before talks take place.
