Yahoo News asked Trump whether this level of tracking might require registering Muslims in a database or giving them a form of special identification that noted their religion. He wouldn’t rule it out.

“We’re going to have to — we’re going to have to look at a lot of things very closely,” Trump said when presented with the idea. “We’re going to have to look at the mosques. We’re going to have to look very, very carefully.”

Attention Muslims! There’s a meeting

At City Hall tomorrow night.

Donald Trump will be there tweeting

Out his views on civil rights.

Afterwards we’ll have inspection.

Take a moment to attach

To your shirt, for your protection

This yellow star-and-crescent patch.

Every Muslim now will need ’em

We’ll check for them at traffic stops

They signify that you hate freedom

To our friendly local cops.

And in the subway, street, or mall

If someone curses, yells, or teases

Here’s a number you can call:

It’s 1-800-Come2Jesus.

And we’ll be happy to escort you

As long as you’re not coming back

To an airport, to deport you

To Syria or to Iraq.

 You’re going off where you can live

According to your sacred text.

No need to thank us, or forgive.

And you can guess who’s going next.
