Monday morning, Trump unleashed a round of tweets blaming Mexico and the Democrat party for contributing to America’s Dreamer crisis, picking up a thread he began Sunday on the same subject.

DACA (Deferred Action for Childhood Arrivals), the controversial policy created extralegally by President Obama, was rightly kicked to the legislature to legally codify protections for individuals who were brought to the U.S. as children without any legal immigration status.

Late last week, it was reported that a “caravan” of close to a thousand Central Americans were marching through Mexico and onward to the southern U.S. border. Their goal is “to cross our border by seeking asylum, crossing illegally, or by exploiting the ongoing “catch and release” policy,” Fuzzy Slippers blogged Sunday.

Sunday, Trump tweeted.

And then picked up where he left off Monday morning:

When the Trump Administration announced the cancellation of DACA, they indicated they would support legislation that provided similar protections. A legislative deadline of March 5 was set. That deadline has come and gone and Congress has yet to act.

During the Omnibus Spending Bill press conference, Trump lashed out at Democrats for refusing to include DACA protections among the bill’s hodgepodge of provisions, accusing them of political posturing.
