She had been shot by a Russian soldier,” Christie said. “In her hands was her leash with her dead dog at the end of that leash. She was out walking her dog and was shot and killed by a Russian soldier.”Christie made mention of thousands of children said to have been abducted from Ukraine by the Russian army.“(They were) stolen from their families and taken back to Russia to reprogram them to be anti-Ukraine,” Christie said. “I met one of those mothers whose child was taken away from her. They don’t know where their child is, if their child’s dead or alive, being cared for, abused.”The Republican invoked Ron DeSantis and Donald Trump when describing the nature of what Ukraine is up against in the war.“This is the regime that Ukraine is fighting. This is not a territorial dispute, Gov. DeSantis. This is not something we should ignore, Donald Trump,” Christie said. “This is something that America stands up against, and those folks deserve and have earned our support.”See his full answer in the video player below: Regarding climate change, Christie cautions against abandoning certain energy sources, touts use of nuclear powerOne voter questioned former Christie about his thoughts on aiming to achieve net-zero emissions by 2050.The Republican said he favors an “all-of-the-above strategy” with energy.“We can’t disarm ourselves economically while we convert to cleaner energy,” Christie said. “We can’t have our aspirations outstrip our innovation.”Christie argued for expanding the use of nuclear power.“I’ve watched the example in my home state. We are the most densely populated state in America,” Christie said. “And we have gotten 53% of our electricity annually from nuclear.”“Nuclear can really help us reach both reliability and to get down to net zero on carbon, we need to continue to support and develop wind and solar,” Christie said.Christie said New Jersey was the second-largest solar-producing state in the country when he was governor.“I really felt like we should push the edge of the envelope on that because of how densely populated you are. We had a lot of space that we could put these, you know, reflectors on and be able to gather that energy,” Christie said.Oil and gas would remain key energy sources as part of his administration’s approach, Christie added.See his full answer in the video player below:See the full "Conversation with the Candidate" event through the following links:Watch Part 1: Christie blasts Trump, Biden over their families’ wealth gainsWatch Part 2: Christie wonders why other Republicans won't confront Trump moreWatch online exclusive: Christie says he, Scott might be only Republicans who seek unityOther "Conversation with the Candidate" events will be held throughout the campaign season.
