James Comer, the Kentucky Republican leading the Trump administration’s investigation into Joe Biden’s use of an autopen, has himself used digital signatures on official correspondence related to the probe, according to NBC News.
Metadata analysis of 16 letters sent by Comer to former Biden White House officials requesting transcribed interviews showed that all appeared to be signed with a digitally inserted signature. Additional letters to White House physician Dr Kevin O’Connor and senior aide Anthony Bernal also bore digital images.
The findings risk undermining Republican efforts to scrutinise Biden’s mental fitness, with Donald Trump claiming the former president was unaware of what he signed. Biden has dismissed the allegations as “ridiculous and false”, insisting he made every decision personally.
A spokesperson for the House oversight committee, which Comer chairs, defended the practice, stating that digital signatures are common for correspondence. However, they stressed that legally binding subpoenas always carry a wet signature.
