Missing Saudi writer case stirs US boycott calls

A leading U.S. senator says Treasury Secretary Steven Mnuchin shouldn't attend a major investment conference in Saudi Arabia later this month in the wake of reports that journalist and U.S. resident Jamal Khashoggi may have been killed at the Saudi consulate in Istanbul.

Florida Republican Marco Rubio tells CNN's "State of the Union" that he doesn't think any U.S. government officials "should be going and pretending as it's business as usual, until we know exactly what's happened here."

But White House economic adviser Larry Kudlow says the conference will deal with terrorist financing and how to stop it, and that "at the moment," Mnuchin intends to go.

Kudlow tells ABC's "This Week" that Mnuchin "will make up his mind as the week progresses and as new information surfaces" and the investigation proceeds.
