As more Democrats join the parade of liberal pols calling for the end of the federal Immigration and Customs Enforcement (ICE) agency, President Trump is pushing back.

“To the great and brave men and women of ICE, do not worry or lose your spirit,” he tweeted Saturday. “You are doing a fantastic job of keeping us safe by eradicating the worst criminal elements. So brave!”

The anti-ICE message is becoming a liberal litmus test since new Dem darling Alexandria Ocasio-Cortez’s upset victory over Queens power broker Rep. Joe Crowley.

Upping the ante, Trump tweeted that all law enforcement is in the Democrats’ crosshairs.

“Next it will be all police,” he posted. “Zero chance, It will never happen!”

A few minutes later, Trump talked up a deal that would rein in oil prices.

“Just spoke to King Salman of Saudi Arabia,” he tweeted at 7:37 am, “and explained to him that, because of the turmoil & disfunction in Iran and Venezuela, I am asking that Saudi Arabia increase oil production, maybe up to 2,000,000 barrels, to make up the difference…Prices to high! He has agreed!”

Gas prices, which have soared in recent weeks, spiked again Tuesday on news that the State Department is pressuring U.S. allies to cut off all oil imports from Iran – a policy that would sharply restrict global supplies.

Trump grabbed his iPhone Saturday afternoon to post another rash of tweets, promoting a Sunday morning interview with Maria Bartiromo of Fox News (“Enjoy!”) and flogging a new book by former White House press secretary Sean Spicer – “A friend of mine and a man who has truly seen politics and life as few others ever will.”

He slammed Senate voting rules in a tweet that tossed a gratuitous insult at New York Sen. Chuck Schumer.

“Either we need to elect more Republicans in November or Republicans must end the ridiculous 60 vote, or Filibuster, rule – or better yet, do both,” he wrote. “Cryin’ Chuck would do it on day one, but we’ll never give him the chance. Some great legislation awaits – be smart!”

And the president revisited the explosive immigration controversy – making no mention, though, of the day’s hundreds of protests in Washington, D.C., New York and elsewhere.

“When people come into our Country illegally, we must IMMEDIATELY escort them back out without going through years of legal maneuvering,” he tweeted. “Our laws are the dumbest anywhere in the world.”

Contradicting his own Twitter feed, he also claimed to have “never pushed” House Republicans to vote for the hardline enforcement bills introduced by Rep. Bob Goodlatte (R- Virginia) “because it could never have gotten enough Democrats as long as there is the 60 vote threshold” in the Senate.

“I released many prior to the vote knowing we need more Republicans to win in Nov.,” he wrote.

The tweet ran counter to one that Trump posted on Wednesday, urging the GOP – in all caps – to “PASS THE STRONG BUT FAIR IMMIGRATION BILL, KNOWN AS GOODLATTE II… EVEN THOUGH THE DEMS WON’T LET IT PASS IN THE SENATE.”

The bill failed by a wide margin, 121-301.
