Death threats to former Alaska Governor Sarah Palin have increased to unprecedented levels in the wake of Saturday’s shooting in Tucson, an aide tells ABC News.

Following the attack that seriously wounded Democratic Rep. Gabrielle Giffords and killed 6 others, Palin has found herself embroiled in a firestorm of controversy. Numerous left-wing commentators have accused Palin’s hard-hitting partisan rhetoric of influencing accused shooter Jared Lee Loughner.

The Daily Caller reported that dozens of Twitter users called for Sarah Palin’s death in the hours following the shooting, with some going so far as to wish for her assassination.

On his Monday radio broadcast, media personality Glenn Beck read from an e-mail he wrote to Palin in which he urged the former Republican presidential candidate to protect herself and invest in more security. “An attempt on you could bring the Republic down,” Beck wrote.
