A prosecutor with special counsel Robert Mueller's office says Cohen "has provided consistent and credible information about core Russia-related issues under investigation."

NEW YORK (AP) - A judge sentenced President Donald Trump's ex-lawyer Michael Cohen to three years in prison Wednesday.

A prosecutor with special counsel Robert Mueller's office says Cohen "has provided consistent and credible information about core Russia-related issues under investigation."

Jeannie Rhee didn't elaborate on that information as she spoke Wednesday at Cohen's sentencing. But she did say that Cohen "has sought to tell us the truth, and that is of the utmost value to us."

The 52-year-old Cohen served as Trump's personal lawyer and self-described fixer. Cohen has pleaded guilty to dodging taxes, lying to Congress and violating campaign finance laws.

He told the judge during sentencing he felt it was his duty to cover up president's "dirty deeds" and that "blind loyalty" to Trump "led me to take a path of darkness instead of light."

Cohen took "full responsibility" for crimes including campaign finance violations, lying to Congress, bank fraud and evading $1.4 million in taxes.

He could get about four to five years in prison, but his lawyer is arguing for leniency.

His attorney, Guy Petrillo, says Cohen "came forward to offer evidence against the most powerful person in our country" when he cooperated with prosecutors. But a prosecutor on the case against Cohen says Cohen's crimes showed a pattern of deceit, brazenness and greed.
