We caught up with him Sunday. Here is a transcript of the interview, which has been condensed and lightly edited.

What made you decide to challenge a sitting senator?

The state has changed significantly over the past 25 years. We are overdue for a real debate on the issues, priorities and leadership the voters want from their senator. California deserves a senator that will not just fully resist the Trump presidency, but also understand the issues that most Californians face every day.

Do you think Senator Feinstein is out of touch with the Democratic Party?

I don’t want to get into her right now. I promise you I will give you more as we go on in the next few days or next few weeks.

Do you think that her age — 84 — should be an issue?

Absolutely not. Her problem isn’t age, but where she stands on the key issues that the voters care about. Ideas and values and priorities.

What issues do you differ with her on? Is Trump one of them?

My record is very clear on where I have stood with regards to Donald Trump and how he is a clear and present danger to economic prosperity, to progressive values and to our people. I don’t believe that Dreamers have the patience to wait to see if Donald Trump will be a good president.
