WASHINGTON -- Special counsel Robert Mueller's office says it plans to call 35 witnesses in the upcoming trial of U.S. President Donald Trump's former campaign chairman.

Prosecutors with the special counsel filed the witness list Friday in the case of Paul Manafort. The 35 names include former accountants, assistants and even friends.

Among the witnesses is Rick Gates, Manafort's deputy and co-defendant, who pleaded guilty this year and agreed to co-operate.

Also on the list is Tad Devine, a strategist on Bernie Sanders' Democratic presidential campaign but also a participant in Manafort's Ukrainian political work.

Manafort is accused of routing millions of dollars in proceeds from Ukrainian political consulting work into offshore accounts and using the money to fund a lavish lifestyle.

Jury selection is scheduled to start Tuesday in Alexandria, Virginia.
