UA1648 right now. @united worst gate agent experience ever in Aruba. Family of 4 on paid tix. 2 paid 1st and 2 paid economy. 2 of us are global services. I’m 3M miler. Seat 1B broken (arm rest wobbled literally). Seat 2B and 3B also broken. Gate agent let the two 15 year olds board but would not let the two adults on paid 1st tix board. Did not ask for volunteers. Would not talk to global services desk that I had on the phone. We were only able to board when another family De-planed because they would have been separated.

What a terrific (and obvious in the rear view mirror) technological improvement over the use of…the ears!
We backed Eko Health because their tech saves lives — and now the NHS is proving it. Early heart failure detection, fewer emergency visits, and £100M in potential savings. This is what meaningful innovation looks like. Proud to be investors in a company reshaping cardiac care. #PortfolioNews #venturecaptial #PROOF #healthcare

Well I guess that @Sec_Noem has already started this process. xitter.cf/Sec_Noem/status/192561…
One overreaction deserves another. Let’s stop issuing student visas. 300,000 students are here on student visas from China alone. That is $30B per year going to the universities. From China. Shut off that spigot and the universities will lean on the judges overnight

BREAKING: A federal judge in California has issued a nationwide injunction that will block the Trump administration from ending legal status for foreign students attending schools in the US while the underlying case is being litigated. Judge Jeffrey White says the government cannot arrest or imprison "any of the named Plaintiffs in these cases and similarly situated individuals nationwide pending resolution of these proceedings..."

Defunding is a start. but we also need to create a "do not fund" list so that they get no new federal dollars for the next 4 years. Oh, and let's not forget about taxing university endowment income! And while we are at it, why not let the universities backstop any student debt that their students default on.
And no one or organization on campus should be taking money from said government, nor should they get a tax break from the citizens who are taxed to pay that “private” institution. Defund Harvard.

We believed in Keller’s vision back in 2016 when we first invested. This is the future. THIS is the way.
Today, Zipline launched in Dallas, our first major metro in the US. We’re seeing the dawn of a new era of robotic instant logistics that is going to become an indispensable part of our lives. After 4 years and hundreds of thousands of test flights, teleportation is finally here.

+1 from a 2 Jeep and 1 Tesla household.
I always wonder why wealthy folks don’t buy American cars. My family drives all @ford. They work great. Is it really better spend more to import Land Rovers, Mercedes, Lexuses, etc. and drive the equivalent of a Gucci purse? It is in our best interest to keep US workers working. I understand folks who are struggling to make ends meet buying a cheaper car from Korea. But the rich? Nope.

I love this idea. It channels my inner Milton Friedman. Let the free markets rule! Along a similar vein can we also auction to the highest bidder the spectrum currently given to legacy broadcast tv media?
Send all of em back. Auction off citizenship/Visas to highest bidder. Google can bring in engineers. Charitable donors can bring in asylum seekers. Government can't buy any. Cap number to be sold at say 750,000 per year. If you sponsor an immigrant and pay for their Visa/citizenship, you are also financially responsible for any liabilities, damages, govt subsidies incurred by this new resident for say 10 years. Immigration becomes a profit center, sponsors are invested and liable, gang members and criminals will not be let in. True asylum seekers can be let in by charitable folks. Market for VISAs insures the most worthy or productive get in. Thoughts?

Scott, I think you need to work for the new DOGE - Department of Government Efficiency. I’ll join you!
De-scope the feds, send 80% of the scope and workers to the states. Cut the fed tax rate so the states can tax locally for what they need in their state. Dissolve most cabinet portions and eliminate the department. Start with the fbi

Powerful. Brave. Speaking truth to power. Time for a new movement. Time to "defund the schools" of indoctrination. It starts with donors. Just say no. @ShaiDavidai
To the presidents of @Columbia, @nyuniversity, @Harvard and other universities who have stood SILENT as terror supporters have marched through campus and celebrated raping women, executing children and kidnapping grandmothers, you are cowards. Listen to Columbia Professor and father @ShaiDavidai’s heartbreaking speech:

Look who was on my plane today from DC to San Francisco. Escorted by 5 armed security people to a waiting 2-car caravan. Who is paying for this? I thought Fauci was “retired?” Enjoy @JebraFaushay
