Congressional Oversight of the Antiquities Act

HR 2645 would amend the Antiquities Act to impose a six-month expiration on national monuments established by presidential proclamation, or until the end of the current congressional session, whichever comes first. If Congress does not extend a monument during this period, the same land cannot be designated as a national monument for 25 years. This bill directly affects the President's authority to create new national monuments and the land within those designations. The change would require congressional action to maintain monument status rather than allowing it to remain in effect indefinitely.
