Government shutdown updates: Leavitt says Trump exploring cutting aid to Portland

As the clock ticks down toward a government shutdown, 150 House Democrats, including House Minority Leader Hakeem Jeffries, gathered on the House steps on Tuesday morning ahead of the government funding deadline -- with Jeffries addressing a deepfake video generated by artificial intelligence shared by President Donald Trump.

The video, shared by Trump on Monday night, disparages Jeffries and Senate Minority Leader Chuck Schumer.

"Mr. President, the next time you have something to say about me, don't cop out through a racist and fake AI video. When I'm back in the Oval Office, say it to my face!" Jeffries said.

Jeffries added that Democrats are "ready" to find a bipartisan path to avert a shutdown -- as he sharply criticized House Republicans for canceling votes this week.

Miami Dade College will be the location for President Donald Trump's presidential library, according to an announcement on Tuesday.

The president selected the location after his son Eric Trump -- who is the president of the Library Foundation -- and his team "evaluated multiple sites across President Trump's home state of Florida."

"No monument can fully capture the scale of my father's legacy, but this library will stand as a tribute to the leader who reshaped history and restored America's strength," Eric Trump said in the announcement.

The library, which will sit on a 2.63-acre site, will be "visible for miles into the Atlantic" and will be a "bold landmark on Miami's skyline," Eric Trump said.

While holding a press conference announcing a deal with Pfizer to lower drug costs, President Donald Trump was asked if a government shutdown is inevitable, to which he replied: "Nothing is inevitable, but it is probably likely."

Trump added that "we can do things during the shutdown that are irreversible," as the government funding deadline approaches.

In a press conference at the Oval Office, President Donald Trump announced that Pfizer has "agreed to provide some of the most popular current medications to all consumers at heavily discounted prices of anywhere between 50 and even 100%."

He said this deal with Pfizer will have a "huge impact on bringing Medicaid costs down like nothing else."

Trump also announced that Pfizer will invest $70 billion for manufacturing and research in the United States.

The CEO of Pfizer, Albert Bourla, was in attendance for the announcement, and said they are "turning the tide and reversing an unfair situation."

The medications will be available for direct purchase online on a website, which will be called Trump Rx, that will be operated by the federal government, according to the Director of Medicare and Deputy Administrator of CMS Chris Klomp.
