Erika Kirk, the widow of conservative activist Charlie Kirk, will attend Trump’s State of the Union address as a guest, according to the White House.

The president will use Kirk’s attendance to say there has been a “tremendous revival of faith, Christianity, and belief in God in our country” and to call on Congress to “firmly reject political violence against our fellow citizens,” the White House confirmed.

Kirk was named the new CEO and chair of the board for Turning Point USA after her husband was shot and killed while speaking at a campus event in Utah last September.

Other guests include the parents of Sarah Beckstrom, the West Virginia National Guard member who was killed in an ambush in Washington last November. First lady Melania Trump will bring two guests who will help highlight her AI and foster care initiatives, her office said.

The Long Island Rail Road announced it will suspend service systemwide beginning at 1 a.m. Monday due to the expected blizzard conditions.

“The Long Island Rail Road is the busiest commuter railroad in North America, carrying approximately 250,000 customers each weekday on 947 daily trains,” according to New York’s Metro transit Authority.

New Jersey Transit similarly announced that it will suspend its bus and light rail commuter service beginning at 6 p.m. Sunday.

New York City Mayor Zohran Mamdani announced earlier Sunday that roads in the city, including highways and bridges, would be “closed to all vehicles,” including cars, trucks, scooters and e-bikes, beginning at 9 p.m. through noon on Monday in anticipation of the blizzard, except for “essential and emergency trips.”

Mamdani also declared a local state of emergency due to the blizzard, including cancelling school Monday.

DNA was recovered from several gloves and other pieces of potential evidence, and those DNA samples are now being compared to samples taken from associates of Nancy Guthrie, Pima County Sheriff Chris Nanos told ABC News Friday.

The sheriff said he is hopeful investigators are “getting closer” to solving the case.

“We’ve gotten DNA back,” Nanos said.

“They already have the genetic markers of those that we think had access to the home,” he said, including members of Guthrie’s family and household help.

“Now we have to go through and try to eliminate people,” Nanos said.

Several gloves have been found throughout an expanded search zone within a 10-mile radius of Guthrie’s home, the sheriff said. No gloves were found at her house.

Investigators planned to return to Guthrie’s house as soon as Friday to take additional measurements from the front doorway, where the suspect lurked. They have estimated his height to be 5 feet 9 to 5 feet 10 inches, and now the hope is to determine the man’s weight.

“It is really about just taking that video and frame-by-frame and trying to get as much out as we can,” Nanos said.

Other investigators are trying to trace the point of sale of the backpack sold at Walmart the suspect was seen carrying.

Walmart declined to comment on whether it is assisting the investigation.

The individual detained earlier this week for questioning in Rio Rico, Arizona — who identified himself as Carlos — is not fully cleared even though he has been released and is under no law enforcement restrictions, the sheriff said.

“Nobody’s fully cleared,” Nanos said. “He talked with us, he was cooperative.”

Nanos said the sheriff’s department and FBI are working side-by-side to find Nancy Guthrie.

“We’re not giving up,” Nanos said. “If Nancy’s out there, we’re going to find her. We’re not giving up.”
