WATCH: Dem. Rep. snatches phone in testy airport exchange over Biden's mental clarity: 'Who owns you?'
Democratic Rep. Marcy Kaptur got into a contentious exchange with a man at a Detroit airport who asked her about President Biden's cognitive abilities after Thursday's debate.
FIRST ON FOX: Longtime Democratic Rep. Marcy Kaptur was captured on video Friday losing her patience with a man who asked her whether President Biden should step down following his widely panned CNN debate performance.
"Excuse me congresswoman, should Joe Biden step down?" A man in the Detroit airport asks Kaptur in video obtained by Fox News Digital.
The 78-year-old congresswoman ignores the question as she is going up the escalator through the airport, which prompts the man to repeat the question.
After Kaptur doesn't respond for a second time, she is asked, "Why has the White House been lying about Joe Bidens' cognitive abilities?"
Kaptur, who appears to be adjusting her luggage, then stares into the camera before grabbing the phone in the man's hands as the video cuts out.
"Congresswoman why did you take my phone like that?" Kaptur is asked in a follow-up video as she walks through the airport.
"What is your name? Kaptur responds looking directly into the camera. "Where do you live?"
"Why are you asking me all these personal questions, congresswoman?" The man responds.
"Because you're asking me questions," Kaptur says.
As the two slowly spin in a circle, Kaptur asks, "Where do you live? Where do you live? What town?"
"I don't have to tell you that information," the man says, which causes Kaptur to say, "Then I'm not answering you."
As Kaptur again starts walking away, the man again asks, "I just want to know, congresswoman, should Joe Biden step down?"
"No," Kaptur responds before continuing to walk away.
The two continued to go back and forth with Kaptur asking the man why he is "reading questions off that sheet" and "who owns you?"
"Nobody owns me," the man responds. "I'm just curious on some questions."
"They own you," she says as she walks out of the airport doors.
In a statement to Fox News Digital, Kaptur campaign spokesperson Alexandra Wilcox said, "It’s one thing to ask a question but an unknown man refusing to identify himself, forcing a camera in the Congresswoman’s personal space is another thing entirely."
"The man has still not identified himself or the organization for which he works."
Wilcox continued, "All these politics aside, Congresswoman Kaptur remains fully focused on delivering further transformational federal investment to Northwest Ohio."
Democrats, particularly those in competitive elections this November, have been facing questions about Biden's debate performance and specifically where he should step aside in the 2024 race.
Many Democrats have acknowledged that Biden did not have a good night, including former President Barack Obama who said on Friday, "bad debate nights happen."
Kaptur, who has served in Congress for 21 terms, is facing a tough re-election race in Ohio's 9th Congressional District that Cook Political Report ranks as a "Democrat Toss Up."
