Asked about the presumptive GOP presidential nominee after she delivered remarks in Philadelphia on Monday, the Federal Reserve chair said she and her colleagues weren't making predictions about the effects of a Trump White House.
"I'm sorry, I've got nothing for you on that," she said when asked about the chances of a global "economic crash" following a Trump victory.
"We're very focused on doing our jobs, and we'll just — we'll see what happens," she added amid others' clapping and laughter in the room.
Trump has previously said he would be inclined to replace Yellen as the Fed chair. Last year he alleged the Fed had kept rates low to help President Barack Obama's administration.
"They are not raising them because Obama has asked them not to raise them," Trump said in November. "In my opinion he wants to get out of office because we are in a bubble and when those rates are raised, a lot of bad things are gonna happen."
