Wednesday afternoon, Sen. Bernie Sanders tweeted the following:

During his campaign for the Democratic presidential nomination, Sanders often made an issue of high drug prices. And recently, Sanders noted that the price of epinephrine injectors, a.k.a. "Epi-Pens," which millions of Americans depend on as a lifesaving measure in case they have an allergic reaction, appear to have been artificially inflated:

Just this morning, Bloomberg reported the following (as noted by Geoffrey Norman in THE WEEKLY STANDARD):

Members of Congress are in an unusual position as they demand an explanation for Mylan NV's 400 percent price hike for the EpiPen and focus attention squarely on its CEO: Heather Bresch. If lawmakers follow the usual script, Bresch could get called up to Capitol Hill next month to explain her company's justification for raising the price on the life-saving allergy shot. But that could be awkward, since she's the daughter of Democratic senator Joe Manchin of West Virginia.

It would seem that Sanders's tweet about CEO salaries is a pointed message directed squarely at his Democratic colleague in the Senate.
