One of the Senate’s newest members was months late disclosing 700 personal stock trades that together are worth millions of dollars, according to a NOTUS review of new congressional financial records.

Sen. Alan Armstrong (R-Oklahoma), who entered the Senate on March 24 after Markwayne Mullin vacated his seat to become homeland security secretary, made a flurry of stock purchases and sales in the several days after his swearing in.

But the senator, a wealthy businessman who served as CEO of the oil and gas company Williams Companies until 2025 and as executive chairman thereafter, didn’t publicly disclose his financial moves until this week — more than two months past a 45-day deadline mandated by the Stop Trading on Congressional Knowledge Act.
