MILWAUKEE -

U.S. Sen. Ron Johnson wants answers from the Veterans Administration after a Wisconsin veteran killed himself.

Johnson on Friday sent a letter to Veterans Affairs Secretary Robert McDonald, asking for all documents about 29-year-old Brian Rossell of Wausau, whose body was found Thursday in Lake Wausau. Rossell's mother said her son had sought help from the Tomah VA this summer and was turned away.

Johnson chairs the Senate Homeland Security and Governmental Affairs Committee. In his letter, Johnson says Rossell's apparent suicide "underscores concerns that the VA has yet to take full ownership of the systemic failures of the Tomah" facility.

The Tomah facility was dubbed "Candy Land" by some veterans for its prescribing practices.

The VA did not immediately respond to requests from The Associated Press for comment Saturday.
