On Monday's broadcast of CNBC's "Squawk Box," White House National Economic Council Director Lael Brainard reacted to negative poll numbers on the economy by stating that "the economy is performing exceptionally well" but "people have been through a very challenging few years between the pandemic, and then the oil price spikes associated with Russia's war. It's going to take a while for them to feel really confident," and most people "feel like their personal finances are better now than they were before."
