He can take it upon himself to ignore lawyers. No doubt. He should ignore them. I agree he should challenge the War Powers Act but other Presidents have ignored it as well. He should have Holder take it to court and get it thrown out, but like other Presidents he doesn’t want a fight with Congress he can avoid by just ignoring the law.
Which other Presidents have ignored it? They all say they don’t like it, but this seems unprecedented. Besides not following the law, Obama didn’t even consult with Congress, IIRC.
1981: President Reagan deployed a number of U.S. military advisors to El Salvador but submitted no report to Congress. Members of Congress filed a federal lawsuit in an attempt to force compliance with the Resolution, but the U.S. District Court hearing the suit declined to become involved in what the judge saw as a political question, namely whether U.S. forces were indeed involved in hostilities.
1982-83: President Reagan sent a force of Marines to Lebanon to participate in peacekeeping efforts in that country; while he did submit three reports to Congress under the Resolution, he did not cite Section 4(a)(1), and thus did not trigger the 60 day time limit. Over time the Marines came under increasing enemy fire and there were calls for withdrawal of U.S. forces. Congress, as part of a compromise with the President, passed Public Law 98-119 in October 1983 authorizing U.S. troops to remain in Lebanon for 18 months. This resolution was signed by the President, and was the first time a President had signed legislation invoking the War Powers Resolution.
1990-91: President George H.W. Bush sent several reports to Congress regarding the buildup of forces in Operation Desert Shield. President Bush took the position that he did not need "authority" from Congress to carry out the United Nations resolutions which authorized member states to use "all necessary means" to eject Iraq from Kuwait; however he did ask for Congressional "support" of U.S. operations in the Persian Gulf. Congress passed, and the President signed, Public Law 102-1 authorizing the President to use force against Iraq if the President reported that diplomatic efforts had failed. President Bush did so report, and initiated Operation Desert Storm.
1993-99: President Clinton utilized United States armed forces in various operations, such as air strikes and the deployment of peacekeeping forces, in the former Yugoslavia, especially Bosnia and Kosovo. These operations were pursuant to United Nations Security Council resolutions and were conducted in conjunction with other member states of NATO. During this time the President made a number of reports to Congress "consistent with the War Powers Resolution" regarding the use of U.S. forces, but never cited Section 4(a)(1), and thus did not trigger the 60 day time limit. Opinion in Congress was divided and many legislative measures regarding the use of these forces were defeated without becoming law. Frustrated that Congress was unable to pass legislation challenging the President's actions, Representative Tom Campbell and other Members of the House filed suit in the Federal District Court for the District of Columbia against the President, charging that he had violated the War Powers Resolution, especially since 60 days had elapsed since the start of military operations in Kosovo. The President noted that he considered the War Powers Resolution constitutionally defective. The court ruled in favor of the President, holding that the Members lacked legal standing to bring the suit; this decision was affirmed by the U.S. Court of Appeals for the District of Columbia. See Campbell v. Clinton, 203 F.3d 19 (D.C. Cir. 2000). The U.S. Supreme Court refused to hear an appeal from this decision, in effect letting it stand. http://www.loc.gov/law/help/war-powers.php
