He says his administration is running like a fine-tuned machine despite media reports of chaos. Trump's comments come amid a period marked by leaks, division and a couple of high-profile exits.

President Trump also announced Thursday Alexander Acosta as his new pick for labor secretary. Acosta is the dean of the Florida International University law school. The announcement comes one day after his first pick, fast food executive Andrew Puzder, withdrew.

Hundreds of people in Chicago are rallying at a demonstration to mark a day without immigrants. Similar demonstrations are planned nationwide. Numerous businesses and immigrant-heavy industries like restaurants are closing in solidarity.
