We do agree that our country must take action to address climate change.

I am convinced that if we do not decisively win the struggle over the nature of America, by the time [his grandchildren are] my age they will be in a secular atheist country, potentially one dominated by radical Islamists and with no understanding of what it once meant to be an American.

I do not believe that the people of the United States are going to take people who have been here a quarter century, who have children and grandchildren, who are members of the community, who may have done something 25 years ago, separate them from their families, and expel them.

To suggest that it's OK to assassinate a president, I think is a felony. And I think that it should be.

I don't see how the party that says it's the party of the family is going to adopt an immigration policy which destroys families that have been here a quarter century.

Change is healthy and useful. It has to be fought for most of the time. It's not inevitable. It takes real leadership and real effort. But I think it's really important not to take yourself too seriously. Dwight Eisenhower used to have a rule that you should always take your job seriously but not yourself.

Donald Trump has a grand direction. He doesn't have a grand strategy. He wants to re-establish American authority and power and to relaunch the American economy.
