The ranking member of the House Oversight Committee says he has new documents that appear to show former National Security Advisor Mike Flynn lied to investigators who were conducting his security clearance review. In a letter today to the committee’s chairman Rep. Jason Chaffetz, R-Utah, Rep. Elijah Cummings, D-Maryland, urged the oversight chairman to subpoena the White House for documents that detail its process for vetting Flynn. While the White House has largely blamed the Obama administration for failing to vet Flynn, Cummings, citing investigators' records, claims Flynn lied to officials who interviewed him in February of 2016 as part of his security clearance renewal. Flynn appeared to tell investigators his trips to Russia and other countries were paid for by American companies.
