Sheriff David Clarke had resigned as Milwaukee County sheriff on Thursday afternoon.
It is unclear why Clarke decided to resign.
On Sunday, President Trump promoted Clarke’s book, “Cop Under Fire: Moving Beyond Hashtags of Race, Crime and Politics for a Better America.”
A great book by a great guy, highly recommended! https://t.co/3jbDDN8YmJ
