The House Oversight and Reform Committee voted on Thursday to authorize subpoenas for senior White House officials’ communications via private email accounts and messaging applications, a significant escalation in a years-long, bipartisan effort to learn more about potential violations of federal record-keeping laws.

Thursday’s vote by the Democrat-led panel came after the White House refused to turn over the messages voluntarily earlier this month — including senior adviser Jared Kushner’s WhatsApp communications with foreign officials, senior adviser Ivanka Trump’s use of a private email account to conduct official business, and former chief strategist Stephen Bannon’s use of a personal mobile device for White House business.

…On a party-line vote, the committee authorized Cummings to subpoena all communications sent or received since President Donald Trump took office that were not forwarded to official email accounts within 20 days, as required by law. Cummings can also subpoena information about whether those messages contained classified information.
