WATCH: Spicer addresses ousted national security adviser Flynn at news briefing

White House Press Secretary Sean Spicer is expected to address an assertion by the House Oversight committee that former national security adviser Michael Flynn may have broken the law by sidestepping disclosure forms at his Tuesday news briefing.

The White House is refusing to provide lawmakers with information and documents related to President Donald Trump’s first national security adviser’s security clearance and payments from organizations tied to the Russian and Turkish governments.

The White House was responding to requests made last month by the House Oversight committee. The committee made six requests, and the White House cited reasons it could not comply with each of them.

Trump has said he fired Michael Flynn because of misleading comments he made to the vice president about his discussions with the Russian ambassador during the transition. Flynn is among the Trump associates being investigated by Congress and the FBI for possible ties between the Trump campaign and Russia.
