She’ll be expected to implement policies that help shore up a battered economy, sell President Joe Biden’s $1.9 trillion COVID-19 stimulus package to Congress, refocus on the effects of climate change on the economy, unwind contradictory and overlapping sanctions imposed by the Trump administration, and revamp the Bank Secrecy Act’s (BSA) anti-money laundering (AML) program.
