Sam Clovis is a top Trump campaign surrogate emerging at the center of Special Counsel Robert Mueller's current focus. Reports have pegged him as the "campaign supervisor" in Mueller's indictment with whom George Papadopoulos corresponded regarding meetings with suspected Russian officials — and, just last week, he was interviewed by Mueller's team and testified before a grand jury, per NBC News.

Keep an eye out: Clovis is currently nominated to become the USDA's top scientist — though he has no agricultural science or research experience — and the position requires Senate confirmation. Expect fireworks if Democrats on the Agriculture Committee got the chance to question him in a public confirmation hearing.
