Politico is reporting that President Trump’s big announcement, which he teased this week, may relate to Medicare prescription drug prices.

Here’s what they write:

President Donald Trump plans to revive an effort to dramatically slash drug costs by tying the amount the government pays for some medicines to lower prices abroad, three people familiar with the matter told POLITICO.

Trump early next week is expected to sign an executive order directing aides to pursue the initiative, called “most favored nation,” for a selection of drugs within the Medicare program. The idea would use the administration’s authorities to force prices down.

The proposal has not been finalized and could still change as aides work through the specifics, said the people involved in the plan, who were granted anonymity to describe internal deliberations. Trump has not yet personally approved the plan.

The president on Tuesday teased a “very big announcement” within the next week that one of the people familiar characterized as a reference to the drug pricing proposal. The other two did not know whether it was the big announcement but confirmed the drug price plan was likely to be announced in the next week.

“We’re going to have a very, very big announcement to make — like as big as it gets,” Trump said. “It will be one of the most important announcements that have been made in many years about a certain subject.”

Should Trump go ahead with the order, it would represent a major confrontation between the White House and the deep-pocketed pharmaceutical industry.

This would be a big deal and it kind of makes sense give how Trump wants to even things out for America. In this case, he’s likely wanting the pharmaceutical industry to be more fair to the American people and to stop overcharging us, especially as it relates to older Americans on Medicare.

It’ll be interesting to see if this is indeed the ‘big announcement’ or if this is something else entirely.
