Donald Trump is on a tear through the agency formed to protect Americans against enemies of our nation.

He has fired (essentially) the secretary of homeland security, gotten rid of the Immigration and Customs Enforcement agency, canned the Secret Service director. There are threats of more dismissals/resignations to come.

Republican senators are shaking their heads, according to Politico. Sen. Joni Ernst of Iowa said she thought DHS Secretary Kirstjen Nielsen was doing a “fantastic” job.

Sen. John Cornyn of Texas said “It’s a mess,” referring to the border situation and the confusion and chaos at DHS.

Yep, it’s a mess, all right.

I believe that is exactly how Donald Trump prefers it.

Cohesion and smooth operation? Forget about it! Yet he calls his administration a “fine-tuned machine.” The president is not hearing the clanks and misfires from the political “engine” he has built.

I guess I’m allowed to wonder how all this tumult at Homeland Security is going to affect the agency’s ability to, um, secure the homeland.
