The memorandum from the President addresses a backlog in processing security clearances for Executive Office of the President personnel, which is preventing them from performing their duties. To address this issue, the President orders immediate granting of interim Top Secret/Sensitive Compartmented Information clearances to certain personnel for up to six months. The White House Counsel is given authority to adjust this list and revoke clearances if necessary. This memorandum does not create any legal rights or benefits enforceable against the U.S. government.
Simple Explanation
The President wants to help some workers quickly get special permission to do their jobs while waiting for a more detailed check, like a teacher giving classroom helpers a short-term pass to help out right away. This permission can last up to six months, and only the White House lawyer can change or take it away if needed.
