Patrick Shanahan is a US businessman. He’s deeply linked to the Boeing Copmany and got his first post as a government official in 2017.
Earlier Mattis and US special envoy for the global coalition to defeat ISIS Brett McGurk submited resignation letters to the Trump administration. Most of observers link this situation with the decision of President Trump to pull out troops from Syria.
