A feud between a Detroit businessman and the mayor of Detroit could get more heated on Wednesday.
Bob Carmack plans to hold a news conference Wednesday morning to reveal what he claims is new information about Detroit Mayor Mike Duggan.
The conference follows a request by Duggan on Monday asking Michigan State Police to investigate Carmack over allegations of extortion.
Duggan says the businessman threatened to embarrass him if property disputes with the city were not settled in Carmack's favor.
Carmack has released video he says was recorded by a private investigator he hired to follow the mayor that allegedly shows Duggan visiting a woman in the suburbs.
