President Donald Trump called for a “great rebuilding” of America’s “crumbling infrastructure” in this State of the Union address Tuesday. But when Rep. Alexandria Ocasio-Cortez (D-N.Y.) unveiled her Green New Deal infrastructure plan Thursday, Donald Trump Jr. zapped it as “socialism.”

A joint resolution by Ocasio-Cortez and Sen. Ed Markey (D-Mass.) outlined an ambitious “ten-year national mobilization” plan to build “smart grids” and boost power generated from the sun and wind to as close to 100 percent as possible over the next decade.

Donald Jr. scoffed at the inevitable failure of the idea that sounded to him like “socialism.”
