Why do we hold our politicians to a lower standard of honesty than a news reporter?

Brian Williams the NBC news anchor has been forced to step down for 6 months because he lied about his experience during the Gulf war and the Katrina hurricane. These lies were in the nature of gross exaggerations which were improper but hurt no one. Shame on him.

However President Obama repeatedly lied when he told the American public in an effort to pass ObamaCare that you could keep your doctor and you can keep your insurance and no body can take it away from you.Obama also lied when he assured the public that their insurance premiums would be lower. He also lied when he assured the public in 2007 he was opposed to Gay Marriage when in actuality he was in favor of it.

Obama was involved in the Benghazi cover up which is tantamount to a lie. He also refuses to acknowledge most terrorist acts are committed by Radical Islamic terrorists or telling the American people the Fort Hood killings was work place violence. Such deception is tantamount to a lie.

Hillary Clinton lied when she said she was under sniper fire during her trip to Bosnia and repeated the lie on numerous occasions. She also lied numerous times in connection with the Benghazi attack and her involvement with the security arrangements. Bill Clinton lied when he denied having sex with Monica Lewinsky and got away with it.

Why is it that Brian Williams a news anchor whose program is somewhat associated with the entertainment industry has been taken to the wood shed for somewhat innocuous exaggerations or lies while high level politicians repeatedly lie on important matters with impunity?
