The special counsel overseeing the investigation into former President Donald Trump's attempts to remain in power has subpoenaed Ivanka Trump and Jared Kushner to testify before a federal grand jury. The investigation is looking into Trump's role in inciting the Capitol insurrection on Jan. 6, as well as his attempts to remain in office after losing the election. It is unclear if executive privilege will be invoked to block their testimony, or if they will provide any new information to the investigation.
