  • Marco Rubio says he does not agree with President Donald Trump's call for China to investigate Joe Biden. 
  • He previously suggested Trump only made the request to "provoke the news media." 

Sen. Marco Rubio went further than he previously had Tuesday in criticizing President Donald Trump's call for China to investigate Joe Biden — though he said he still thinks the White House will not follow through on the request.

"I don't think what he said was right. I don't agree with it," the Florida Republican told CNBC's "Squawk Alley," days after he said Trump only made his remarks to "provoke" the media.
