The Republican-controlled U.S. House of Representatives kicked off a process on Wednesday that could lead lawmakers to censure Democrat Al Green, who was kicked out of the chamber after yelling at President Donald Trump during an address.

You don’t have a mandate,” yelled Democratic Rep. Al Green of Texas, who stood up holding out his cane and pointed it at the president, after Trump recounted his election win. Republicans stood and chanted “USA” to drown him out.

President Donald Trump made it about four minutes into his first speech to Congress before a Democratic lawmaker, Rep. Al Green, began shouting that he should be impeached.
