The House Judiciary Committee launched a wide-ranging investigation Monday into President Trump, his businesses and his allies, as lawmakers probe possible obstruction of justice, corruption and other crimes and abuses of power. The committee requested documents from at least 81 people or groups, who now have a March 18 deadline to respond. The list includes his sons Donald Trump Jr. and Eric Trump, his son-in-law and senior adviser Jared Kushner, WikiLeaks, AMI chief David Pecker, the Department of Justice, the FBI, Trump’s charities and the founder of private security firm Blackwater, Erik Prince—who is also the brother of Education Secretary Betsy DeVos.
