WASHINGTON (AP) — Trump administration officials said they’re crafting a new legislative package aimed at closing immigration “loopholes” following the president’s calls for Republican lawmakers to immediately pass a border bill using the “Nuclear Option if necessary” to muscle it through.

“As ridiculous as it sounds, the laws of our country do not easily allow us to send those crossing our Southern Border back where they came from. A whole big wasted procedure must take place. Mexico & Canada have tough immigration laws, whereas ours are an Obama joke. ACT CONGRESS!” President Donald Trump wrote in a series of continual, sometimes-misleading tweets Monday after a weekend in Florida with several immigration hardliners.

Trump also declared protections for so-called Dreamer immigrants “dead,” accused Democrats of allowing

“open borders, drugs and crime” and warned Mexico to halt the passage of “caravans” of immigrants or risk retribution.

“Honduras, Mexico and many other countries that the U.S. is very generous to, sends many of their people to our country through our WEAK IMMIGRATION POLICIES,” he wrote. “Caravans are heading here. Must pass tough laws and build the WALL.”

Trump has been seething over immigration since realizing the major spending bill he signed last month barely funds the “big, beautiful” border wall he has promised his supporters. The $1.3 trillion funding package included $1.6 billion in border wall spending, but much of that money can be used only to repair existing segments, not to build new sections.
