In mid-March, with the American economy in free fall, Jeffrey Sprecher, husband to Sen. Kelly Loeffler (R-Ga.) and chair of the company that owns the New York Stock Exchange, made an unusual change to his stock portfolio: He started buying.

For weeks, the couple had done almost nothing but sell. Loeffler was one of several senators who faced public outrage for unloading millions of dollars in stock before most Americans understood the towering threat posed by the coronavirus pandemic. Then shortly before the CARES Act, a $2 trillion emergency stimulus package, was introduced in the Senate, her husband reversed course and purchased up to $1 million in new shares, a HuffPost investigation has found.

The terms of the CARES Act were still mostly a secret, known primarily to Republican senators while members of their party crafted the legislation. But in the days before the bills introduction, Sprecher managed to invest in several industries insurance and energy that were poised to take advantage of the bills very specific provisions.

Those purchases are just the latest to raise questions about whether Loeffler, the Senates richest member, has ever used the insider knowledge she gleans on Capitol Hill to inform her own portfolio. Loeffler is locked in an intense runoff election in Georgia that will help decide which party controls the U.S. Senate when President-elect Joe Biden is sworn into office, and her challenger, Democrat Raphael Warnock, has made accusations that she uses her seat for personal enrichment a constant theme of his attacks.
