Money, drugs and tax evasion: The second Hunter Biden trial is set to begin Thursday

Hunter Biden is on trial in Los Angeles for a second time this week for tax evasion.

He was convicted this summer on gun charges; now he faces allegations of criminal tax evasion in a second case.

Prosecutors say he avoided paying $1.4 million in taxes he owed for tax years 2016 through 2019 .

During that time, prosecutors say, Biden earned more than $7 million , including for work with Ukrainian energy firm Burisma Holdings Limited , a now-bankrupt Chinese energy company and a Romanian oligarch facing bribery allegations.

Biden is set to be sentenced on Nov. 13 after a jury convicted him on all charges in a gun-purchase case.

Biden 's defense has been trying to argue that he was debilitated by his addiction when he allegedly committed the tax crimes.

A judge threatened to sanction Biden ’s lawyers for making false statements.

Prosecutors say Biden 's associate signed a deal with Popoviciu to provide real estate management services.

That deal resulted in a $3.1 million payment to the associate, who passed on roughly a third of it to Biden , prosecutors say.

Biden also worked with CEFC China (a Chinese energy conglomerate) and Burisma .
