Dennis Hastert was Republican Speaker of the House from 1999 onward (the closing years of the Clinton administration and all of the Bush Jr. administration), following Newt Gingrich.
|from The Highway Robber, #1 in Rolling Stone's The Ten Worst Congressmen:
Hastert could well be the weakest House speaker in history. Tapped by Tom DeLay to serve as the mild-mannered frontman for the GOP leadership, the former wrestling coach ceded most of his power to the now-disgraced majority leader, allowing Republicans to treat the Capitol as their private piggy bank. Last year, Hastert got in on the action himself, secretly inserting $207 million into the budget for the "Prairie Parkway" – a highway that will speed development of 210 acres he owns in Illinois. Before the year was out, Hastert sold part of his land – soon to be the site of a sprawling subdivision – for a profit of $2 million.
