The legal problems for Rep. Maxine Waters, D-Calif., might have taken a turn for the worse, officials said.

The House ethics committee has approved a forced, indefinite leave by two of the lead investigators on the panel investigating alleged wrongdoing by Waters on behalf of a bank, The Washington Post reported.

Zoe Lofgren, D-Calif., said "materials" have surfaced that require an investigative subcommittee to take up Waters' alleged ethics violations once again.

The investigative subcommittee recommended in August that Waters be tried on ethics charges for helping a troubled, minority-owned bank in Boston in which her husband held a large investment.
