MILWAUKEE (WTAQ) - Mark Neumann – who finished third among four candidates in last month’s Republican U.S. Senate primary – is asking for about $152,000 in unexpected campaign bills.

The Waukesha County homebuilder and former congressman e-mailed supporters Monday to say he needs help to pay some unexpected bills from vendors late in his campaign. And Neumann said he had no money left in his campaign account to cover those bills.

Neumann’s net worth is between $6 million and $18 million – and as of late July, he put $240,000 of his own money into the campaign. But Neumann told the Milwaukee Journal Sentinel he would not cover the last-minute bills with his money.

He said he was trying to help GOP Senate nominee Tommy Thompson raise campaign money for his November contest against Democrat Tammy Baldwin.

Neumann said the e-mail solicitation would not cut into his efforts to help Thompson.
