Received an email from the U.S. Treasury, or so it says, wanting me to log in to my account and confirm my bank account.

"To check your bank account information on file, log into TreasuryDirect (we recommend typing “TreasuryDirect.gov” directly in your web browser)...

They don't want me to use the provided link, then why provide it? I'm not sure why they are sending this unsolicited email. The IRS doesn't send unsolicited emails. Why is the Treasury? What are they selling? What problem are they trying to correct (or causing)? Is the President going to try and sell me his bitcoin?
