Suspended state Sen. Leland Yee is due back in federal court for his alleged role in a San Francisco political corruption and organized crime case.

Yee could enter pleas Tuesday to one count of conspiracy to traffic in firearms without a license and to illegally import firearms, and to six counts of engaging in a scheme to defraud citizens of honest services.

The San Francisco Democrat is accused of conspiring to connect an undercover FBI agent with a Philippine arms dealer in exchange for campaign contributions, and of trading political influence for cash.

Yee and 19 others were formally indicted last week after being arrested on March 26.

Other defendants, including Raymond "Shrimp Boy" Chow, whose charges include money laundering and trafficking, are scheduled for arraignment Tuesday.
