Giving the guy her keys to the office and wiping down his fingerprints would make her an accessory at the very least.
It would sure seem so. I found this story after posting the one about Cosko and wondering why she had been named but not charged. That changed today. From the sounds of it and the timing, she took a plea deal to avoid more serious charges.
A lesson she apparently did not get in college: that Congress works for The People.
