President Bush visited Chicago's O'Hare Airport today where he urged Americans to get back in the air. Seeking to soothe a nation left anxious about air travel, the President outlined a broad strategy for tightening aviation security, including temporarily sending National Guard troops to major airports. Governor Jesse Ventura announced he would move quickly to dispatch Minnesota troops to the Minneapolis-St.Paul International Airport. Democratic Senator Mark Dayton sent a letter to Bush earlier this week suggesting the National Guard idea. He says he's not sure if the President took his advice OR if he had already planned on using the troops at airports, but Dayton says he's pleased with Bush's decision.
