President Donald Trump said he will investigate former President Joe Biden using an autopen during his time in the White House.
"We're going to start looking into this whole thing with who signed this legislation. Who signed legislation opening our border? I don't think [Biden] knew. I said, 'There's nobody that can want an open border. Nobody,'" Trump said while visiting Capitol Hill Tuesday. "And now I find out that it wasn't him. He autopenned it."
Trump said he wants to know who was operating the autopen.
"This is a very serious thing," Trump said. "We had a president that didn't sign anything. He autopenned almost anything. He opened the borders of the United States of America."
House Oversight Committee Chair James Comer, R-Ky., said Friday that the panel has opened an investigation into former President Biden's use of an autopen to issue his eleventh-hour pardons, adding he thinks they know the staffer who did it, the Washington Examiner reported.
Biden earned Trump's ire back in January when he used the autopen for preemptive pardons for his family members in the waning hours of his presidency. Also getting pardons before Biden left the White House were members of former House Speaker Nancy Pelosi's, D-Calif., Jan. 6 select committee; Dr. Anthony Fauci, the former director of the National Institute of Allergy and Infectious Diseases; and Gen. Mark Milley, chair of the Joint Chiefs of Staff.
Trump declared the pardons issued by Biden "void, vacant, and of no further force or effect" because they were signed by a device.
