RICHMOND, Va. (AP) — The nation’s largest tobacco companies are challenging court-ordered advertisements requiring the cigarette makers to say they lied about the dangers of smoking.

The so-called corrective statements are part of a case the government brought in 1999 under the Racketeer Influenced and Corrupt Organizations Act. U.S. District Judge Gladys Kessler ruled in 2006 that the nation’s largest cigarette makers concealed the dangers of smoking for decades and has since ordered them to pay for the statements in various advertisements in newspapers, as well as on TV, websites and cigarette pack inserts.
