U.S. prosecutors on Monday plan to wrap up their tax and bank fraud case against former Trump campaign chair Paul Manafort, making it likely the case will go to the jury by midweek if the defense decides not to call any witnesses.

The trial is in its 10th day in Alexandria, Virginia, federal court and is not scheduled to resume until Monday afternoon, Reuters said. The case arose from U.S. Special Counsel Robert Mueller's probe of Russian meddling in the 2016 presidential election.

Before completing their case, prosecutors will call James Brennan, an executive at the Federal Savings Bank. On Friday, a former salesman at Federal testified that the bank's chief executive personally approved $16 million in loans to Manafort while seeking Manafort's help getting a post in President Donald Trump's cabinet.

The prosecution also wants to recall Paula Liss, an agent with the Treasury Department's Financial Crimes Enforcement Network. The defense is seeking to block further questioning of her, and the judge has not yet ruled. Liss testified last week that Manafort did not disclose his foreign bank accounts.

Manafort's lawyers will then face a choice: call their own witnesses or hope the prosecution's case is not strong enough to outweigh defense attacks on the credibility of Rick Gates and the testimony of more than two dozen other witnesses.

Gates testified last week that Manafort, his former boss, directed him to help commit the tax and bank frauds, but the defense portrayed him as living a "secret life" of infidelity and embezzlement.

Prosecutors contend Manafort hid a significant portion of the approximately $60 million he earned as a consultant for pro-Russian politicians in Ukraine, then lied to borrow millions more in a bid to maintain an extravagant lifestyle when the Ukraine work dried up.

If the defense decides not to call any witnesses, the court may on Monday hold a conference with the lawyers to decide what instructions should be given to the jury before they begin deliberations, Judge T.S. Ellis said on Friday.

Closing arguments may take place on Tuesday. Ellis ordered each side to limit its summation to two hours.

It was unclear if Ellis makes public the reason behind an unexpected recess on Friday that lasted into the midafternoon and included a lengthy discussion with the lawyers and judge at the bench, the contents of which remain under seal.

Some legal experts have speculated that it may have been triggered by a problem with the jury after Ellis reminded jurors in unusual detail and multiple times about the defendant's presumed innocence, the need to "keep an open mind" about the trial and not to talk to anyone about the case.
