When you're offered a job to serve your country, you step back and assess. And once I spoke with President Trump and told him what I thought I needed to be successful - which was to be a Cabinet member; to be on the National Security Council, where I could be a part of the policy decisions; and to be able to say what I wanted to say - how do you not do that job? He was incredibly supportive. He's continued to be. I love a good challenge, and this certainly has been that.
