Ten­sions in Los An­ge­les es­ca­lat­ed Sun­day night as thou­sands of pro­test­ers took to the streets in re­sponse to Pres­i­dent Don­ald Trump’s de­ploy­ment of the Na­tion­al Guard, block­ing off a ma­jor free­way and set­ting self-dri­ving cars on fire as law en­force­ment used tear gas, rub­ber bul­lets and flash bangs to con­trol the crowd.

What to know:

Troop de­ploy­ment: Trump has in­voked a le­gal pro­vi­sion al­low­ing him to de­ploy fed­er­al ser­vice mem­bers when there is “a re­bel­lion or dan­ger of a re­bel­lion against the au­thor­i­ty of the Gov­ern­ment of the Unit­ed States.” Rough­ly 300 Na­tion­al Guard mem­bers ar­rived in the city over the week­end, and Trump said he had au­tho­rised 2,000 mem­bers to de­ploy if need­ed.

Gavin New­som: This ap­pears to be the first time in decades that a state’s Na­tion­al Guard was ac­ti­vat­ed with­out a re­quest from its gov­er­nor. In a let­ter Sun­day af­ter­noon, the Cal­i­for­nia gov­er­nor re­quest­ed that Trump re­move Na­tion­al Guard mem­bers, call­ing their de­ploy­ment a “se­ri­ous breach of state sov­er­eign­ty.”

Trav­el ban: As ten­sions con­tin­ue to rise over Trump’s im­mi­gra­tion en­force­ment, the Pres­i­dent’s new ban on trav­el to the U.S. by cit­i­zens from 12 main­ly African and Mid­dle East­ern coun­tries is tak­ing ef­fect Mon­day.

The city of Glen­dale can­cels a con­tract that al­lows ICE to house de­tainees in its lo­cal jail

The city in Cal­i­for­nia is can­celling a con­tract that al­lowed fed­er­al im­mi­gra­tion au­thor­i­ties to house de­tainees with­in its lo­cal jail, cit­ing fears of un­der­min­ing com­mu­ni­ty trust.

In a state­ment Sun­day night, Glen­dale of­fi­cials said the city would for­mal­ly ter­mi­nate its agree­ment with the De­part­ment of Home­land Se­cu­ri­ty and U.S. Im­mi­gra­tion and Cus­toms En­force­ment.

“[T]he City recog­nis­es that pub­lic per­cep­tion of the ICE con­tract—no mat­ter how lim­it­ed or care­ful­ly man­aged, no mat­ter the good—has be­come di­vi­sive,” the state­ment not­ed.

Fed­er­al im­mi­gra­tion au­thor­i­ties of­ten en­ter in­to agree­ments with lo­cal po­lice de­part­ments to house im­mi­grant de­tainees. ICE’s agree­ment with Glen­dale had been in place since 2007, of­fi­cials said.

An ICE spokesper­son did not im­me­di­ate­ly re­spond to a re­quest for com­ment.

“AR­REST THE PEO­PLE IN FACE MASKS, NOW!” Trump wrote at 12:19 a.m.Trump cit­ed Los An­ge­les Po­lice Chief Jim Mc­Don­nell’s re­cent com­ments to de­fend his re­sponse to the protests.

“Don’t let these thugs get away with this. MAKE AMER­I­CA GREAT AGAIN!!!” Trump wrote at 12:14 a.m.

“This thing has got­ten out of con­trol,” Mc­Donell said Sun­day.

“We have great cops in South­ern Cal­i­for­nia here that work to­geth­er all the time,” he said. But he added that “look­ing at the vi­o­lence tonight, I think we got­ta make a re­assess­ment.”
