The main purpose of this legislation is to officially designate June 14, which is both Donald Trump's birthday and Flag Day, as a legal public holiday in the United States. The objective is to recognize and celebrate these two occasions on the same day. The key provision of this legislation is the amendment to the United States Code, specifically title 5, which outlines the legal public holidays. It adds June 14 as a new holiday, following Memorial Day. This means that June 14 would be recognized as a day off for federal employees and potentially influence state and local observances as well.
