The truth is that, in trying to get at terrorists who are in countries that either are unwilling or unable to capture those terrorists or disable them themselves, there are a lot of situations where the use of a drone is going to result in much fewer civilian casualties and much less collateral damage than if I send in a battalion of marines.

We know the battle ahead will be long, but always remember that no matter what obstacles stand in our way, nothing can stand in the way of the power of millions of voices calling for change. We have been told we cannot do this by a chorus of cynics. They will only grow louder and more dissonant. We've been asked to pause for a reality check. We've been warned against offering the people of this nation false hope. But in the unlikely story that is America, there has never been anything false about hope.

Battling terrorism must go beyond belligerence vs. isolation.

By 2016, the people who had looked to [Barack] Obama for change were looking somewhere else.

I could say, as a member of Congress, we usually get an alert if something is going to happen at the Capitol.

Maybe at the same time as I'm more confident today, I'm also more humble.

The fact is every single day in the ordinary American people, America's families have to make decisions about their families and that should be made by them, not by the Texas or United States.
