"British Citizen and CNN television host Piers Morgan is engaged in a hostile attack against the U.S. Constitution by targeting the Second Amendment," the petition states. "We demand that Mr. Morgan be deported immediately for his effort to undermine the Bill of Rights and for exploiting his position as a national network television host to stage attacks against the rights of American citizens."
Morgan has battled pro-gun advocates several times on "Piers Morgan Tonight" in the wake of the Newtown shooting, even calling one gun lobby director a "dangerous man" who brings "shame" on his country.
"How many more kids have to die before you guys say, 'we want less guns, not more'?'" Morgan asked Gun Owners of America head Larry Pratt earlier this week.
More than 7,000 people had signed the petition as of Saturday afternoon. It would require 25,000 signatures by Jan. 20 to garner an official White House response.
The petition was apparently created by Kurt Nimmo of the website infowars.com.
Morgan acknowledged the petition on Twitter Saturday, tweeting at one point: "6,600 Americans have currently signed the petition to deport me - meaning 311,993,400 clearly want me to stay. Thank you."
In another tweet he said it was ironic that the petition-signers would have him deported for using the First Amendment to express his views.
"Ironic U.S. gun rights campaign to deport me for 'attacking 2nd Amendment rights' - is my opinion not protected under 1st Amendment rights?" Morgan wrote.
