House Majority Leader Steny H. Hoyer said Thursday he and Speaker Nancy Pelosi made a mistake when they called "tea party" participants "un-American" last year. "That was not a good phrase, not a good use of language, it was not correct," Mr. Hoyer, Maryland Democrat, said, adding that he did not see anything wrong with vigorous debating of philosophies. Mr. Hoyer and Mrs. Pelosi wrote an op-ed article... "Drowning out opposing views is simply un-American," the two wrote. The charge became a rallying cry for tea partiers.
