In January 2019, Warren criticized Trump's decision to withdraw U.S. troops from Syria and Afghanistan. She agreed that U.S. troops should be withdrawn from Syria and Afghanistan but said such withdrawals should be part of a "coordinated" plan formed with U.S. allies. In April 2019, after reading the Mueller Report, Warren called on the House of Representatives to begin impeachment proceedings against Trump, saying, "The Mueller report lays out facts showing that a hostile foreign government attacked our 2016 election to help Donald Trump and Donald Trump welcomed that help. Once elected, Donald Trump obstructed the investigation into that attack."
