Need To Know.
Ex-Intel Agent Accused of Espionage.
A former US counterintelligence officer was charged with sharing classified information with the Iranian government, according to documents released yesterday. 39-year-old Monica Witt, who defected to Iran in 2013 while still a member of the Air Force, allegedly revealed details of a secret Defense Department program to Iranian officials. She was also accused of giving the personal details of intelligence assets in the region, which hackers - four of whom were also indicted - used to target them online. Witt remains out of the reach of the Justice Department, presumably still residing in Iran. The news came as Secretary of State Mike Pompeo kicked off a forum on Middle East issues in Poland (without some key players), and reports surfaced that a covert US program to thwart Iranian missile development was being restarted (paywall). 

Separately, a suicide bombing carried out by the Sunni militant group Jaish al-Adl killed 27 members of the elite Iranian Revolutionary Guard near the border with Pakistan. 
One Year Later.
 Today marks the one year anniversary of the mass school shooting at Marjory Stoneman Douglas High School in Parkland, Florida in which 17 people were killed and 17 others injured. The massacre spurred a wave of student-led activism and calls for changes in gun laws at the state-level across the nation. In one of the more notable changes, the Florida state legislature approved a "red flag" law, allowing law enforcement to confiscate firearms from people exhibiting violent behavior without having courts adjudicate the matter. The shooter, 20-year-old Nikolas Cruz, is still awaiting trial - his defense has suggested he will plead guilty in exchange for a life sentence, though prosecutors have suggested they will seek the death penalty. 

Check in with teacher Ernie Rospierski, hailed as a hero after putting himself between Cruz and fleeing students during the attack. 
Judge Says Manafort Lied in Probe.
A federal judge concluded that Paul Manafort lied to investigators in Special Counsel Robert Mueller's probe into potential Russian meddling in the 2016 election. The false statements allegedly came after he had entered a cooperation deal with investigators, and the decision lowers the chances that the former Trump campaign chairman will receive a reduced sentence, which is expected to be handed down next month. Manafort was found guilty on multiple charges of bank and tax fraud last fall - the specific charges were unrelated to his role with the Trump campaign. Judge Amy Berman Jackson agreed with prosecutors that Manafort misled investigators about conversations with Konstantin Kilimnik, who has ties to Russian intelligence (Manafort said he simply forgot some details about the talks).
