Trump's former campaign chairman Paul Manafort is planning to register with the U.S. government as a foreign agent, his spokesman Jason Maloni said Wednesday.

What that means: He would register under the Foreign Agents Registration Act for some of his past political work, namely his role as an international political consultant at his lobbying firm in Ukraine. "The work in question was widely known, concluded before Mr. Manafort began working with the Trump Campaign and was not conducted on behalf of the Russian government," Maloni said in his statement.
