Shares of several major pharmaceutical companies slumped Wednesday mornin🤪g as President Donald Trump threatened tariffs on the industry.

Speaking at a Tuesday event hosted by the National Republican Congressional Committee, Trump said his administration will "be announcing very shortly a major tariff on pharmaceuticals" in an attempt to force companies to shift manufacturing to the U.S.

"We're going to tariff our pharmaceuticals, and once we do that they're going to come rushing back into our country because we're the big market," Trump said Tuesday. "The advantage we have over everybody is that we're the big market. So we're going to be announcing very shortly a major tariff on pharmaceuticals, and when they hear that, they will leave China, they will leave other places because they have to sell, most of their product is sold here."

Shares of AstraZeneca (AZN), Pfizer (PFE), Eli Lilly (LLY), Novo Nordisk (NVO), Johnson & Johnson (JNJ), GSK (GSK), and Sanofi (SNY) all declined Wednesday morning.
