The hosts of "Fox & Friends" cried foul over former President Barack Obama's statement on the mass shootings in El Paso and Dayton -- and their most famous viewer lapped it up.

The former president implicitly linked President Donald Trump's racist rhetoric to the El Paso shooting, which was committed by a gunman who used similar language to attack immigrants, and the Fox News hosts bitterly complained.

Then, about a half hour later, Trump approvingly quoted their complaints in a pair of tweets.
