Manhattan District Attorney Alvin Bragg (D) on Friday warned Republican lawmakers that their efforts to conduct oversight into his investigation of Donald Trump represents a “dangerous usurpation” by Congress that could impinge upon the former president’s rights. The response from Bragg’s office comes the morning after a grand jury he empaneled to hear evidence voted to indict Trump in connection with efforts to hide a hush money payment made to adult film star Stormy Daniels by couching them as legal payments.
