The warrant also demanded that the union provide information about payments and emails to and from consultant Michael Youngblood.

In an interview last week, Youngblood, who was wearing a gold “98” lapel pin, said he did not know why he was named in the warrant. A former boxer, Youngblood worked as a City Council staffer and later as a political activist and consultant. He has twice served time in prison, once for a federal drug conviction in the 1980s and then in 1999 after a conviction for extortion, bank fraud, and tax evasion.
