Fiona Hill: What did Trump mean for America and the world?

The Trump Presidency challenged many public officials to make a choice: obey directives from the White House against their better judgment, or take a stand and face the wrath of the pro-Trump movement. Fiona Hill, a former Russia adviser at the White House, took a stand. She was a key witness in Donald Trump’s first impeachment trial, and has since had time to reflect on what his presidency meant for America and its geopolitical standing.
