Story highlights The Trump Organization leased the property from the GSA in 2013

The GSA's inspector general is conducting a formal review of how the agency has handled the lease

Washington (CNN) The General Services Administration's Office of Inspector General is now undertaking a formal review of how the agency has handled President Donald Trump's Washington hotel lease.

"GSA's Office of Inspector General (OIG) is evaluating GSA's management and administration of the ground lease for the Old Post Office Building," the agency's spokeswoman Pamela Dixon told CNN on Tuesday.

The Government Accountability Office is also conducting a review of GSA's "outleasing program," which covers the Trump hotel lease.

"Our review will be looking generally at the GSA outleasing program. We expect that it will cover a wide range of issues and leases," explained GAO spokeswoman Jennifer Ashley in a statement to CNN Wednesday. "But the work is not focused on any one lease."
