Every US president has told a lie — from war and taxes to health conditions and extramarital affairs. When Dwight D. Eisenhower was caught lying by Russia, he said it was his greatest regret in office. "Every president has not only lied at some time, but needs to lie to be effective," Ed Uravic, who wrote "Lying Cheating Scum," told CNN. From President James Polk lying to invade Mexico in 1846 to then-presidential candidate George H.W. Bush famously promising no new taxes, here are some of the most famous lies US presidents have ever made.
