Dana Rohrabacher -- 'Putin's favorite congressman' -- loses to Democrat Harley Rouda

Rep. Dana Rohrabacher -- infamously known as "Putin's favorite congressman" -- lost his re-election campaign in California.

The Republican lawmaker was narrowly defeated by Democrat Harley Rouda, a real estate executive and former Republican, in the deeply conservative 48th House District.

Rohrabacher has been a staunch supporter of President Donald Trump, and he earned his nickname after using information he got from the Russian government to promote one of Vladimir Putin's top priorities -- removing the name of murdered lawyer Sergei Magnitsky from a sanctions act.
