What argument does Nixon make to support his position that the WPR is unconstitutional?

Nixon argues that the War Powers Resolution (WPR) is unconstitutional because it infringes upon the President's authority as Commander-in-Chief, a role that the Constitution grants the executive branch. He contends that the WPR imposes undue restrictions on the President's ability to respond swiftly to military threats, thereby undermining national security. Additionally, Nixon asserts that the legislative branch does not have the constitutional power to dictate the terms under which the President can deploy U.S. armed forces.
