He had additionally lined up a formidable roster of supporters — together with Cavalier Johnson, the mayor of Milwaukee — in addition to labor leaders who credited him with being a powerful neighborhood presence.

Chemours is among the many corporations being sued for environmental contamination — together with, final week, by Gov. Tony Evers and Legal professional Normal Josh Kaul of Wisconsin.

Irrespective of. By Wednesday it was sport over. At a information convention in entrance of the Fiserv Discussion board, Barnes praised Lasry’s marketing campaign, saying he departs with out having made any new enemies.
