Senator Richard Blumenthal (D-Conn.) has accused the Department of Homeland Security (DHS) of 'stonewalling' congressional efforts to investigate the July assassination attempt against former President Donald Trump. Blumenthal expressed outrage at DHS's lack of cooperation, stating that the agency has failed to provide necessary documents and information crucial for the investigation. He warned that DHS's continued resistance could fuel dangerous conspiracy theories and undermine public trust. Blumenthal, who chairs the Senate Homeland Security and Governmental Affairs Committee's Permanent Subcommittee on Investigations, indicated he may resort to issuing a subpoena to obtain the needed information. Meanwhile, Trump has criticized President Biden and Vice President Harris for their rhetoric, claiming it has contributed to the political violence against him, especially following a second assassination attempt. The situation highlights the delicate political dynamics surrounding security and accountability in the current administration.
