He's such a phony. His wife's name was Usha Chilukuri when they met. His in-laws names are Radhakrishna and Lakshmi Chilukuri. He was married in a Hindu ceremony presided over by a Hindu priest.

If you're an American unhappy with the current regime but who has not yet managed to vote, read this, quit making excuses, and get moving
I voted for CHANGE - but it was an adventure! After traveling all the way from New York to Israel to vote, I waited an hour with my wife and son, only to be turned away because I didn’t have the right ID (my Israeli passport was being renewed, and my American passport wasn’t accepted).

There was a time, not so long ago, when Republican George W. Bush appointed a Muslim doctor and outstanding scientist Elias Zerhouni, born and raised in Algeria, as Director of the National Institutes of Health (nominated 6 months after 9/11).

I guess “Let them eat cake” is now his motto. We know how that ended.
Trump's affordability message: "You could even come to Mar-a-Lago. You'll be my guest. The problem is that for $5,000 the most you'll be able to buy is a hamburger and maybe a small dessert. I'm not even sure you could buy that! No, don't go there. It's not a good place if you're price conscious."

This is the approximate equivalent of 150 *five year* research projects. That generate zero published information. This just does not happen even with the uncertainties of scientific inquiry.

$533 million wasted but yeah, we need to make NIH more “efficient”.
The Army awarded an artillery shell project to General Dynamics in a rushed process without the typical vetting.
The result: a fiasco in a Texas factory with robots in flames and half a billion dollars in taxpayer funds that yielded no usable shells.

Susan Collins tried to mock her Democratic opponent for being a fifth-generation logger. It backfired.
Now Troy Jackson is firing back, exposing just how out of touch Collins has become with working-class Mainers.
