Washington, D.C. ? California Democrat Maxine Waters faces a House trial this fall on three charges of ethical wrongdoing, setting the stage for a second election-season public airing of ethics problems for a longtime Democratic lawmaker.

The charges focus on whether Waters broke the rules in requesting federal help for a bank where her husband owned stock and had served on the board of directors. She denied the charges Monday.

Persons familiar with the case were not authorized to be quoted by name on allegations not yet made public.

The House ethics committee’s announcement comes just days after it outlined 13 charges against Rep. Charles Rangel, D-N.Y., including failing to disclose assets and income, delayed payment of federal taxes and improper use of a subsidized New York apartment for his campaign office.
