President Trump turned to Twitter to urge Congress to “do your job” about the Deferred Action for Childhood Arrivals program that h​is administration ​is expected t​o end later on Tuesday.

​”​Congress, get ready to do your job – DACA!,” Trump wrote​ on Twitter.​

Attorney General Jeff Sessions is expected to make an announcement about the Obama-era program that prevented the deportation of undocumented immigrants who were brought to the US as children.

​The Trump administration is expected to announce that it is getting rid of DACA but will allow it to continue for another six months so that Congress can act on the program. ​

The action could lead to the deportation of about 800,000 people, know as “Dreamers,” if Congress fails to preserve the program.
