Political consultant Sam Patten sentenced to 3 years probation, per @kpolantz in the courtroom. Patten avoids prison because he helped Mueller and other federal investigators, who vouched for him before sentencing. [...]

Patten must also complete alcohol and substance abuse outpatient programs, as determined by the court's probation office, as well as participate in a mental health program.

Helped how? I don't get it, do you?
