The surveillance only goes one way: towards those suspected of having conservative or pro-Trump (Trump is no conservative) political leanings. From Stephen Katte at The Epoch Times via zerohedge.com:
The Biden administration has been accused by the House Judiciary Committee and its Select Subcommittee on the Weaponization of the Federal Government of conducting unlawful “broad” surveillance of citizens’ private financial data without a warrant and with no evidence of any crimes being committed by the individuals.

In a new interim report released on March 6, and an accompanying press release, the committee claims to have uncovered “startling evidence,” proving the federal government pried into the private transactions of American consumers without specific evidence of any criminal conduct.
According to the report, federal law enforcement, including the Treasury Department’s Financial Crimes Enforcement Network (FinCEN) and the FBI, colluded with large financial institutions in the United States, such as Barclays, U.S. Bank, Charles Schwab, HSBC, Bank of America, PayPal, and many others in what boiled down to a “fishing expedition for Americans’ financial data.”
“Tactics included keyword filtering of transactions, targeting terms like MAGA and TRUMP, as well as purchases of books, religious texts, firearms-related items, and recreational stores, like Cabela’s, Bass Pro Shop, and Dick’s Sporting Goods,” the report said.
“This surveillance extended beyond criminal suspicion, likely encompassing millions of Americans with conservative viewpoints or Second Amendment interests.”
And Julian Assange is in jail for exposing this crime. A law for me and a different law for thee.
