Connecticut Attorney General William Tong Tuesday plans to speak more on what he calls President Donald Trump’s “unconstitutional executive order attacking birthright citizenship.” His press conference is scheduled for 1 p.

A coalition of 18 states filed suit seeking an injunction before the executive order takes effect in February.

Connecticut has joined 17 other states, the District of Columbia, and the city of San Francisco in a lawsuit opposing President Donald Trump’s executive order that seeks to limit birthright citizenship.

HARTFORD - Attorney General William Tong moved quickly Tuesday to challenge an executive order President Donald Trump signed Monday redefining birthright citizenship, calling the presidential action "utterly lawless and unconstitutional.

He also signed an order aimed at ending the longstanding constitutional provision providing “birthright citizenship” to any baby born in the U.S. regardless of the immigration status of their parents. Connecticut’s attorney general, William Tong, promised Monday night he would file suit.

Connecticut Attorney General William Tong, who said he became the first United States citizen in his immediate family because of birthright laws, said the order was “ a war on American people.”

Connecticut was among 18 states to jointly sue President Donald J. Trump on his second day in office Tuesday over his effort to deny the birthright citizenship ensconced in the Constitution and affirmed by the U.

Trump's move has sparked immediate backlash. Connecticut Attorney General William Tong pledged swift legal action, saying, "We will sue imminently."
