An ethics report released Monday found that Rep. Maxine Waters probably broke conflict-of-interest rules in urging federal aid for a bank where her husband had served on the board and owned hundreds of thousands of dollars in stock. The California Democrat, a member of the Financial Services Committee, denied any wrongdoing and said she will not settle with the House ethics committee, most likely meaning a second public trial of a leading Democrat this fall. Rep. Charles B. Rangel (N.Y.) is set to stand trial on allegations that he broke congressional rules with his personal finances and with his fundraising efforts for a New York college.
