The House Judiciary Committee is expected to vote to authorize subpoenas for 12 people mentioned in special counsel Robert Mueller's report , including President Donald Trump's son-in-law, Jared Kushner, and former Attorney General Jeff Sessions.
Lawmakers are also voting Thursday to authorize subpoenas for documents and testimony related to President Donald Trump's handling of immigration, including on the separation of migrant families at the southern border.
The resolution authorizes an investigation into whether there have been any discussions of Trump offering pardons to Homeland Security officials who work on immigration issues.
Judiciary Chairman Jerrold Nadler of New York will make the final decision about issuing the subpoenas and has said they can be avoided if witnesses and the administration cooperate voluntarily.
Trump tweeted about the vote shortly before the meeting began. He said the witnesses "have already spent hours with Robert Mueller, and spent a fortune on lawyers in so doing."
Three other names on the subpoena list are related to the National Enquirer's efforts to help kill potentially embarrassing stories about Trump over the years by paying hush money in a practice known as "catch-and-kill."
