President Trump is claiming a tentative victory on parts of a rebranded NAFTA, with Canada currently on the outside looking in.

• “They used to call it NAFTA... We’re going to call it the United States Mexico Trade Agreement."

The big picture:

• "[Trump's] comments threw the trade agreement’s future into doubt, prompting skepticism among lawmakers who support [NAFTA] and concern among businesses whose supply chains depend on a deal encompassing Canada, Mexico and the United States." [N.Y. Times]
• "In dangling the prospect of a new, bilateral trade agreement, Mr. Trump appeared eager to pressure Canada to come to a quick resolution and accede to many of the United States’ demands." [N.Y. Times]
• "It wasn’t immediately clear how much power the Trump administration has to remove Canada from any deal, given Mexico and Canada have been unified in saying all three countries needed to remain in the agreement." [WSJ]

Details: The understanding with Mexico would require 75% of an automobile's value to be manufactured in North America, up from NAFTA's current level of 62.5%. It would also require 40% to 45% of the car to be made by workers earning at least $16 an hour.

What's next: Negotiations with Canada are expected to begin this afternoon, Axios' Zach Basu reports. Both the U.S. and Mexico have expressed a desire to have Canada join the agreement, but according to the U.S. Trade Representative Bob Lighthizer, the deal is set to be presented to Congress either way.

The White House flag was lowered this afternoon, a reversal to honor Sen. John McCain.

Statement from President Trump:

"Despite our differences on policy and politics, I respect Senator John McCain’s service to our country and, in his honor, have signed a proclamation to fly the flag of the United States at half-staff until the day of his interment.

I have asked Vice President Mike Pence to offer an address at the ceremony honoring Senator McCain at the United States Capitol this Friday.

At the request of the McCain family, I have also authorized military transportation of Senator McCain’s remains from Arizona to Washington, D.C., military pallbearers and band support, and a horse and caisson transport during the service at the United States Naval Academy.

Finally, I have asked General John Kelly, Secretary James Mattis, and Ambassador John Bolton to represent my Administration at his services."
