One more Republican bites the dust

Bye, bye!

Yet another casualty in the Jack Abramoff scandal: Karl Rove's personal aide Susan Ralston has resigned over her ties to Abramoff, the AP reports.

Ralston was Abramoff's personal assistant until she moved over to Rove's office in 2001. Abramoff reportedly bragged to others that Ralston was his "implant" at the White House.

The White House announced an internal ethics investigation of Ralston after a Congressional report released last week showed extensive contacts between Ralston and Abramoff's lobbying team. Among other things, the report showed that Ralston had accepted thousands of dollars in gifts from Abramoff without compensating him. White House ethics rules prevent employees from accepting gifts worth more than $20.
