Good morning.

Here’s what you need to know:

Suspects’ close ties to Saudi prince

At least four people who Turkey says were present at the Saudi Consulate in Istanbul the day a journalist disappeared have close ties to Prince Mohammed bin Salman of Saudi Arabia, The Times has confirmed, and nine worked for the country’s security services, military or ministries.

The Times used facial recognition software, public records, social media profiles and other sources to identify the connections, which undercut suggestions that the crown prince had no knowledge of what happened to the journalist, Jamal Khashoggi. President Trump said on Monday that Mr. Khashoggi may have been the victim of “rogue killers.”

• Support from Trump: The president defended Saudi Arabia on Tuesday as criticism of Prince Mohammed intensified. “Here we go again with you’re guilty until proven innocent,” Mr. Trump said in an interview, apparently drawing a parallel to sexual assault accusations against Justice Brett Kavanaugh.
