Members of the Senate Judiciary Committee, which will begin marking up the Gang of Eight's amnesty bill (S.744) on Thursday, have filed 300 amendments that propose changes to the 867-page legislation. The lion's share of amendments were offered by Republicans on the committee; in fact, the committee's Ranking Member, Sen. Chuck Grassley (R-Iowa), offered almost as many amendments (77) as the committee's entire Democratic delegation (93).
