President Trump on Friday continued his attack against the acquittal of an undocumented immigrant who was charged with murdering a woman in San Francisco — declaring: “BUILD THE WALL!”

In an early morning tweetstorm, he called the jury’s verdict a “complete travesty of justice,” blamed the Obama administration for allowing the defendant to cross the Mexican border and warned Democrats to take a tougher stance on immigration.

“The Kate Steinle killer came back and back over the weakly protected Obama border, always committing crimes and being violent, and yet this info was not used in court,” Trump tweeted.

“His exoneration is a complete travesty of justice. BUILD THE WALL!” he continued.

“The jury was not told the killer of Kate was a 7 time felon. The Schumer/Pelosi Democrats are so weak on Crime that they will pay a big price in the 2018 and 2020 Elections,” he said in another tweet.

The suspect, Garcia Zarate, 45, had said the 2015 shooting death of 32-year-old Kate Steinle on a San Francisco pier was an accident.

Under a sanctuary city law, the San Francisco Sheriff’s Department had released Zarate from jail despite a federal immigration request to detain him for deportation.

Zarate, who was acquitted of murder and manslaughter, had been deported to Mexico on five previous occasions.

Local authorities released him under San Francisco’s sanctuary city law that limits cooperation with federal immigration officers.

Trump also lashed out at the acquittal late Thursday.

“A disgraceful verdict in the Kate Steinle case! No wonder the people our Country are so angry with illegal immigration,” he tweeted.

Steinle’s death galvanized anti-immigration forces and fueled Trump’s call for a border wall on the campaign trail.

On Friday, the president also touted a proposed tax-cut package and blamed “obstructionist” Democrats for trying to derail it.

“Republicans Senators are working hard to pass the biggest Tax Cuts in the history of our Country. The Bill is getting better and better,” he tweeted.

“This is a once in a generation chance. Obstructionist Dems trying to block because they think it is too good and will not be given the credit!”
