House Oversight Committee Chairman James Comer has subpoenaed the Department of Homeland Security (DHS) Secretary, Alejandro Mayorkas, as he claims the government entity he leads has information relevant to his investigation about Democratic Vice Presidential candidate Tim Walz's "connections" to China.
Concretely, Comer claims to have learned through a whistleblower about a "non-classified" group chat comprising DHS personnel that "contains information about Governor Walz that is relevant to the Committee's investigation."
