A powerful House committee has launched an investigation into what it calls “grave breaches of national security” over how White House officials were awarded clearances to read highly classified documents. Democrats on the House Oversight Committee say the White House and Trump’s transition team gave clearances to officials who should not have had access to the nation’s top secrets. Among those cited by the committee: former national security adviser Michael Flynn, who lied to the FBI about secret conversations he held with Russia’s ambassador to the U.S.; former White House staff secretary Rob Porter, who received a security clearance despite allegations of spousal abuse; and President Trump’s son-in-law and senior adviser Jared Kushner, who failed to report over 100 foreign contacts on his initial application for clearance, which he later revised three times.
