President Trump on Thursday dug up a years-old tweet in which former President Barack Obama had called in a State of the Union address for Congress to reform immigration laws.

"I strongly believe that we should take on, once and for all, the issue of illegal immigration. #SOTU," Obama wrote in a Twitter post on Jan. 25, 2011.

"I totally agree!" Trump wrote in a retweet of his predecessor's message.

A partial government shutdown entered its sixth day on Thursday as Trump and Democratic lawmakers remain at an impasse on whether to include border wall funding in a spending package.

In a separate tweet Thursday, Trump reiterated his call for new and replacement wall at the U.S.-Mexico border and pointed to an incident unfolding in California to support his case.

"There is right now a full scale manhunt going on in California for an illegal immigrant accused of shooting and killing a police officer during a traffic stop. Time to get tough on Border Security. Build the Wall!" Trump wrote.

During a press conference Thursday, Stanislaus County Sheriff Adam Christianson said Cpl. Ronil Singh of the Newman Police Department had pulled over a 21-year-old man earlier this week because the pick-up truck did not have a license plate.

During the traffic stop, the unnamed suspect shot Singh. The officer died hours later at a local hospital.

"This suspect ... is in our country illegally. He doesn't belong here. He is a criminal," Christianson said.

The suspect remains at large.
