Donald Trump's surprise promise to a wounded veteran

Sioux City, Iowa (CNN)Donald Trump on Tuesday night did something he doesn't normally do: He stepped off the stage and went into the crowd to speak with a voter.

A question from a wounded veteran on Tuesday compelled Trump to walk off stage and speak with the man, eye-to-eye, and pledge to do his utmost to move his case forward and help him get the care he needs.
"I am going to put pressure on the (Department of Veterans Affairs) like you wouldn't believe," Trump said, asking the veteran for his contact information. "As president, I can guarantee it. As Trump, I can probably say, I'm going to be able to pull it off anyway."
The man was First Sgt. Todd Landen, a 22-year Army veteran. Sitting in his wheelchair in the front row, he asked Trump about his plans to improve health care at the VA -- a topic Trump has often touched on during the campaign.
    "With the current administration, warrior care is lacking to say the least," Landen told Trump. "What else can the Trump administration do better than the Obama administration?"
    Trump was quick to pledge his support.
    "These are our greatest people, the wounded warriors," Trump told the room. "I wanna, I gotta say hello to Todd."
    Landen, who served three tours overseas, was wounded from an IED attack in Iraq, he told CNN in an interview after the rally. Along with his wife, April, and their 8-year-old daughter, Brianna, he moved to Iowa last year, after Landen finished up surgeries and retired from the Army.
    Trump told Landen as president, he would allow veterans to get health care locally by private doctors.
    Afterwards, the Landens said the interaction was unexpected, but one that brought them hope.
    "He has traumatic brain injury, severe PTSD, and has had 21 surgeries on his chest and back," April Landen, who is his full time caretaker, told CNN.
    Todd Landen said the VA system is rife with problems.
    "It's mass care. They're just shuffling us out and crunching numbers, I think," he said. "The real struggle is what insurance do I use. I'm 100% disabled, the VA is supposed to take care of my medical bills, but I have to go to a hospital 100 miles away."
    Neither Landen or his wife have caucused in Iowa before, but said they plan on turning out to support Trump on February 1, no matter what.
    "Every time I've seen Donald Trump, he's mentioned veterans," Todd said. "I haven't seen that from every candidate. And today I sure didn't expect him to come recognize me in front of the crowd."
    When asked what he would like Donald Trump as president, Landen said, "Put me back in the fight."
    "It wasn't my choice to leave -- I didn't leave on my terms," he said. "But when he gets elected, I hope he will drop the hammer on the enemy, get us out of there, and take care of us afterwards."
    Despite Trump's recently sliding Iowa poll numbers, the Landens are optimistic about his chances.
    "As an entrepreneur, I've followed Trump and his business career and I think he's gonna do amazing things for this country," April Landen said. "And because he is supporting himself, we are getting what his true values are."
