A Lancaster man was charged Thursday with trying to threaten U.S. Sen. Dianne Feinstein's life, the Los Angeles County District Attorney's Office said.
Craig Steven Shaver, 47, allegedly e-mailed a threat to the longtime senator on Sept. 30, prosecutors said.
He is set to be arraigned Friday in a Lancaster courtroom on one felony count each of attempted criminal threats and possession of a firearm by a felon.
The criminal complaint alleges that Shaver was convicted in 1991 of grand theft.
He was arrested Tuesday by Los Angeles County sheriff's deputies and has remained behind bars since then in lieu of $50,000 bail, according to jail records.
If convicted as charged, Shaver could face a potential maximum sentence of more than three years in state prison, according to the District Attorney's Office.
