US Secretary of State Marco Rubio leaves after high-level talks on Ukraine and its security, at the French Foreign Ministry in Paris Thursday, April 17.

Marco Rubio serving as both Secretary of State and national security adviser could be "ultimately disadvantageous" to President Trump, says former adviser John Bolton.
