The recently retired senator Dave Schultheis has caused outrage online by comparing President Barack Obama to the 9/11 hijackers on his Twitter page. According to the Denver Westword blog Schultheis’ er witty Tweets, which are on a protected account only available to sanctioned followers, included such gems as “@Sen_Schultheis: Don't for a second think Obama wants what is best for U.S. He is flying the US Plane right into the ground at full speed. Let's Roll.” His devoted followers were evidently so impressed with his remarks that many of them found it necessary to share them with the rest of the Twitter community thus sparking an online backlash. “Yep, Schultheis appears to have compared President Barack Obama to a 9/11 hijacker -- which would seem extreme coming from most people but pretty typical for him. Looks like he hasn't retired from making an ass of himself,” writes Denver Westword.
