Following his arrival to the Caesars Superdome in New Orleans, and a brief tour of the field roughly one hour prior to kickoff, President Donald Trump went to a suite where he was joined by some members of his family and elected officials — including House Speaker Mike Johnson and Sens. Eric Schmitt and Tim Scott.

Trump was accompanied to the Super Bowl by his daughter Ivanka, his son Eric and his daughter-in-law Lara.

He stood for "America the Beautiful" and saluted during "The Star-Spangled Banner."

Trump is the first sitting president to attend a Super Bowl.

On the way to the Super Bowl on Sunday, President Donald Trump claimed that he has spoken with Russian President Vladimir Putin -- although it was unclear when that conversation might have taken place.

"I know you don't want to talk about your conversation with President Putin, but can you clarify whether you've had that since you've been in office, or whether it happened before you became president?" a reporter aboard Air Force One asked Trump.

"I've had it, let's just say I've had it," Trump replied.

The reporter again tried to clarify: "As president?"

Trump spoke over the interjection, adding, "And I expect to have many more conversations. We have to get that war ended. It's going to end."

The comment comes after a New York Post reporter spoke to Trump exclusively aboard Air Force One on Friday and reported that Trump had spoken to Putin on the phone -- but also failed to pin down a specific timeline.

Trump told reporters aboard Air Force One on his way to the Super Bowl that he will announce 25% tariffs on all imports of steel and aluminum on Monday.

Trump said this would apply to all countries but did not make clear when the tariffs would take effect.

The president said he would later in the week announce reciprocal tariffs on any country that has imposed tariffs on the U.S. Trump had previewed this during his press conference with Japanese Prime Minister Shigeru Ishiba last week -- that means matching duties that other countries impose on American products.

“I'll be announcing, probably Tuesday or Wednesday at a news conference, reciprocal tariffs, and very simply, as if they charge us, we charge them,” Trump told reporters.

The moves are the latest in a string of tariffs Trump has threatened. The 25% tariffs that he threatened to impose on Mexico and Canada were paused for 30 days, but Trump went ahead with 10% tariffs on goods from China.

Trump made a brief appearance on the field at Caesars Superdome about an hour before kickoff for today’s Super Bowl in New Orleans.

It wasn’t clear if everyone in the stadium was aware of the president’s presence. Reporters could hear some scattered boos among mostly cheers.
