If the FBI has been investigating Paul Manafort’s connections to Russia for years before he became Donald Trump’s campaign chairman in 2016, did anyone warn the billionaire reality TV star?

That’s what Sen. Chuck Grassley wants to know. And if there was no warning, why not?

Grassley, the chairman of the Senate Judiciary Committee that is investigating Russia’s interference in the election, wrote a letter to FBI Director Christopher Wray on Wednesday for an explanation, CNN reports. 

The FBI has refused to comment so far.

“I write to inquire about whether the FBI ever provided the Trump campaign with a defensive briefing or other warning regarding attempts to infiltrate the campaign by people connected with, or compromised by, Russian intelligence,” Grassley wrote.
