Who is Aaron Lukas?
What we know:
According to the Office of the Director of National Intelligence (ODNI) website, Lukas has worked in the intelligence community for more than 20 years.
Lukas has previously served as a CIA station chief, and as chief of staff at ODNI during Trump’s first term. He was also the deputy senior director for Europe and Russia at the National Security Council. Before he joined the intelligence community, Lukas worked at the Office of the United States Trade Representative and the Cato Institute, where he met his wife.

What they’re saying:
“Aaron understands firsthand the work of intelligence collectors and analysts because he has done it himself,” Gabbard said in a news release announcing Lukas’ confirmation. “I’m confident he will help us bring much needed transformational change, transparency, accountability, and mission focus to the IC.”
“He is certified in the CIA’s most advanced tradecraft and has conducted covert operations and managed liaison relationships around the globe, leveraging his unique training and foreign language skills,” ODNI’s website says.

What we don’t know:

In a post on Truth Social, Trump said “Tulsi has done an incredible job, and we will miss her.”

There had been rumblings that Gabbard would split with Trump after the president’s decision to strike Iran, which caused some division within his administration. Joe Kent, director of the National Counterterrorism Center, announced his resignation in March and said he “cannot in good conscience” back the war.
