In a ceremony behind home plate at aging Comiskey Park, Gov. James R. Thompson signed into law Wednesday night a bill providing the financing to build a new stadium for the Chicago White Sox.

"I want to send the message that Chicago is most American of all cities and Illinois is the most American of all states," Thompson said.

The White Sox had threatened to move to St. Petersburg, Fla., if the Illinois General Assembly didn't come up with a financing package to build the American League team a replacement for 78-year-old Comiskey, the oldest ballpark in the major leagues.

"We don't give up anything in Chicago and we don't let anyone take anything away from us," said Thompson, flanked by Chicago Mayor Eugene Sawyer and White Sox owners Jerry Reinsdorf and Eddie Einhorn.

"We are a two-team city and we will always be a two-team city. You and I will attend a Cubs-Sox World Series," the Republican governor said, in a speech minutes before the White Sox took the field against the Baltimore Orioles.
