From Reddit: "...This guy is an Austrian politician, and this is what he is wearing in the parliament...."
His name is Stefan Petzner, a former journalist turned politician. Wikipedia tells me that the party he represents is economically liberal and socially conservative. The BZÖ party or the "Alliance for the Future of Austria" wants to end the draft, join NATO, establish a flat tax of about 39%, allow the utility companies to go private, and a more moderate stand on immigration.
The Austrians, I am told at Reddit, find him an ultra conservative wheres here in the United States he would probably be considered a moderate liberal.
He apparently has the same taste in shoes as Ryan Lochte.
