Was this just in DC? Last night, during the Big Game, there were two Stephen Miller-toned recruiting ads. One for ICE itself, the other for Bovino's CBP.
Was this just in DC? Or nationwide? Have not seen them mentioned in most discussion of ad strategies. (Otherwise saturated with gambling, AI etc)

What actually happened was that Jennifer was also invited, but when we talked about her participation, we were told "she could go shopping with the other wives." The deep-rooted sexism of the whole enterprise couldn't remain hidden. Jennifer was repulsed, I felt likewise, and we said no.

Some time later we were invited to a conference on Epstein's island. My name is in the files on a list of invitees.
We said no. I would love to say it was because we learned about all the rape and sex trafficking, but that's not actually the reason.

Hey, my name is in the Epstein files! I've told the story before, but should probably re-up.
TLDR: never met the guy, never took (or asked for) any money from him, never visited the island. I was invited to the island, and said no.
It's not that hard to just say no.

When I was growing up, many songs played over the airwaves in Puerto Rico were in English. I did not understand most of the words. I have to be frank, for many I still don’t. But, I enjoyed them and don’t remember complaining about it. I think that is the case for most of the World.

Bad Bunny’s Super Bowl halftime show will be interpreted by Celimar Rivera Cosme into Puerto Rican Sign Language, a unique dialect used on the island that academic researchers and other experts consider endangered.
Bad Bunny’s Sign Language Interpreter Will Make Super Bowl History, Too
Puerto Rican Sign Language is not the same as American Sign Language. Celimar Rivera Cosme will uniquely capture the rapper’s slang for the game’s deaf viewers.

Speaking just for myself, by now I've had my fill of efforts to "understand" people who have stuck with Trump.
We know who they are.
There are more of us than of them.
Just have to make sure that diff keeps showing up in election results. (As it has in virtually all special elections so far.)

We spoke with more than a dozen Trump voters about how they are making sense of the recent events in Minneapolis. Listen to "The Daily."
Why Trump Voters Are Torn Over Minneapolis
Illegal immigration and government overreach are colliding in Minneapolis, fundamentally changing Trump voters’ views of the president.
