Two Republican lawmakers, and no Democrats, are expected attend a meeting that has been scheduled for Thursday to allow them to review classified information relating to claims the FBI used an informant to gather information on Trump's presidential campaign, the White House said on Tuesday.

House of Representatives Intelligence Committee Chairman Devin Nunes and House Oversight Committee Chairman Trey Gowdy, both Republicans, are expected to attend, White House spokeswoman Sarah Sanders told a regular news briefing. FBI Director Christopher Wray, Director of National Intelligence Dan Coates and Acting Principal Associate Deputy Attorney General Ed O'Callaghan are also expected to attend, she said.
