U.S. Ambassador to Russia Jon Huntsman revealed in an interview with Deseret News that he has been diagnosed with stage one melanoma.

The big picture: Huntsman, whose father died from cancer in February, faced calls to resign after the infamous Trump-Putin summit in Helsinki earlier this year, during which President Trump appeared to accept Russia's denials about election interferences over the findings of U.S. intelligence agencies. In response, the ambassador penned an op-ed in the Salt Lake Tribune explaining that he would remain in his post out of commitment to his foreign service colleagues and his country in this "fragile" era of U.S.-Russia relations.
