Trump threatens government shutdown over immigration

President Donald Trump today threatened a government shutdown if the US Congress refuses to back major changes to immigration policies like establishing a merit-based system, saying America is the "laughing stock of the world" due to the "worst" immigration laws.

Trump has repeatedly called for the merit-based system and the chain migration to reduce overall immigration to the US. Earlier this year, the White House released a proposal for merit-based immigration, which floundered in Congress amid tepid support from within the president's own party.

He also launched an aggressive push for additional border security measures early this year which include USD 25 billion toward construction of a wall along the US-Mexico border.

"We're the laughing stock of the world. We have the worst immigration laws anywhere in the world," Trump said, adding the US needs border security.

"Border security includes the wall, but it includes many other things. We have to end the lottery. We have to end the chain migration, which is like a disaster. You bring one person in and you end up with 32 people," Trump said at a White House joint news conference with visiting Italian Prime Minister Giuseppe Conte.

US lawmakers face a spending deadline in September. The federal government has already shut down twice this year, first over a failed deal for Dreamers, young undocumented migrants brought to the country as children, then over a funding bill.

A shutdown was avoided in March after Congress approved a USD 1.3 trillion spending package that would fund the government through the end of September. However, the spending measure did not address immigration and Trump said at the time, "I will never sign another bill like this again."
