ALEXANDRIA, Va. (AP) — The jury in the financial fraud trial of former Trump campaign chairman Paul Manafort has sent a note to the judge on the fourth day of deliberations.

Jurors resumed deliberating Tuesday morning and sent a note to the judge about 90 minutes later. The content of the message wasn't immediately known.

The trial of Manafort is now in its fourth week. Prosecutors say Manafort hid tens of millions of dollars in foreign income from Ukraine. They also say he lied on loan applications to obtain millions more to maintain a lavish lifestyle.

Manafort's attorneys called no witnesses, arguing prosecutors failed to meet their burden of proof.

The trial is the first courtroom test of special counsel Robert Mueller's Russia probe, though the case doesn't involve allegations of Russian election interference.
