"We currently have about 140,000 troops in Iraq. Sending in an additional 20,000-plus would 'substantially enlarge' those forces. Therefore, the Bush administration would require further authorization from Congress for this euphemistic 'surge,' which is really a substantial escalation. Failure to obtain additional authorization from Congress for this substantial enlargement of U.S. Armed Forces in Iraq would constitute an impeachable offense under the terms of the United States Constitution for violating the Constitution's War Powers Clause and Congress's own War Powers Resolution."
