Temporary upgrades for White House security are set to be approved Thursday following several high-profile breaches, with permanent changes to the White House fence expected in fall 2016.
Work begins Friday to beef up security at vehicle checkpoints at the White House Ellipse, and spikes will be bolted to the White House fence in July to deter fence jumpers.
A U.S. Secret Service report said Thursday that the White House security fence has been breached "many times" and the fence needs to be modernized.
The public will be asked to comment next month on potentially dramatic changes to the White House grounds and security.
The National Park Service says it will add signage to the National Mall to help visitors navigate around White House after security changes are made.
