Timeline of Turmoil: The Rollout of Trump's Immigration Order

— -- The weekend after Donald Trump rolled out his controversial executive order on immigration, a chaotic scene ensued in airports across the country.

A chorus of dissenters protested, while confused customs agents asked for clarity on how to proceed.

Civil rights attorneys filed legal challenges, and a federal judge in Brooklyn blocked deportations.

Soon, it emerged that some key members of Trump's own administration, as well as congressional leadership, had not been fully in the loop -- if at all -- on the scope and language of the action taken Friday afternoon.

"The rollout was confusing," House Speaker Paul Ryan admitted at a press conference this morning. "But on a go-forward basis I’m confident that Homeland Security Secretary Kelly is going to make sure this is done correctly, that they get a good review, and that we are going to make sure we get this program up and running with the kind of vetting standards we want to see."

Here's what we know about how the order was rolled out:

At 4:39 p.m. on Friday at the Pentagon, Trump appeared to take action on his 2016 campaign promise to impose tougher immigration laws, signing an executive order that promised to keep “radical Islamic terrorists out of the United States of America.”
