Tom Llamas showed support for colleague and friend Savannah Guthrie during NBC News' coverage of the State of the Union. "As we cover this - and if you're an NBC News viewer, you usually watch these special nights - Savannah Guthrie is usually here anchoring all of our special political coverage," Llamas, 46, said during NBC's prime-time coverage of President Donald Trump's speech on Tuesday, February 24. "She, of course, is dealing with the unthinkable right now." Savannah's mother, Nancy Guthrie, was reported missing in Arizona on February 1 after she was last seen one day prior. Despite the Guthrie family offering a $1 million reward for the recovery of Nancy, 84, police have yet to identify a person of interest or suspect in the case. "We know you're out there, Savannah. We know you might be watching," Llamas said. "We just want to let you know we are praying for you and your mom. We know you're going to get back here at some point. These nights are not the same without you, but we completely understand what you are going through right now." White House Sends Support to Savannah Guthrie's Family Amid Search for Mom While covering Trump's speech at the United States Capitol in Washington, D.C., Llamas and his colleagues were spotted wearing yellow ribbons, which have become a symbol of hope for the Guthrie family. According to Llamas, the gesture was "following the lead" of what Savannah's Today show colleagues started earlier in the month. During the February 18 episode of Today, Hoda Kotb explained to viewers why they may be seeing a bit more yellow on the set of NBC's morning show. "So many people [are] placing yellow flowers near Nancy's home and all across the city [of Tucson, Arizona]," Kotb, 61, shared. "We got a suggestion from one of our viewers here, we're doing the same here. Yellow roses around Studio 1A and we're all wearing ribbons as we send our love to Savannah and her family." Tom Llamas Courtesy of NBC News/YouTube Hours before the State of the Union, Savannah asked for the public's help in locating her mother. In an emotional Instagram video, the journalist also expressed gratitude for all the prayers her family has received. "We still believe. We still believe in a miracle," she said. "Someone knows how to find our mom and bring her home." Savannah added, "We also know that she may be lost. She may already be gone. She may have already gone home to the Lord that she loves and is dancing in heaven with her mom and her dad and with her beloved brother, Pierce, and with our daddy. If this is what is to be, then we will accept it. But we need to know where she is. We need her to come home." How Nancy Guthrie's Neighbors Are Supporting Savannah and Her Family According to the Today show, the FBI received "more than 750 tips related to Nancy's disappearance" following Savannah's latest message. "There are some people who are close to what happened who know what happened," former FBI supervisor Jason Pack shared with NBC News. "They now have a decision to make, and this decision was really [affected] by this reward."
