Tina Smith introduced the Postal Delivery Accountability Act this week, a bill designed to force the U.S. Postal Service to answer for delivery failures. The name lands with some irony against her own financial disclosures: three stock sales on a single day in March, a banking-sector sell that trailed the S&P 500 by 13.4 points in thirty days, and a scored trade record of zero wins out of four. If accountability is the theme, the filings are happy to cooperate.
The Bill That Got Her Into the News
Smith introduced S. 4672, the Postal Delivery Accountability Act, putting her name in the news cycle on a bill that would require the Postal Service to report delivery metrics and face consequences for falling short. The legislation sits squarely in constituent-services territory: Minnesota is a big state, rural in large stretches, and slow mail is not an abstract grievance.
Social chatter around Smith this week has been less about postal reform and more about Minnesota Democratic politics. She appeared alongside gubernatorial candidate Peggy Flanagan at the state party convention, and her name keeps surfacing in lists of Minnesota Democratic figures whose alignments in the 2026 cycle matter. The postal bill is the policy news. The convention optics are the political news. Neither is the most interesting thing Blind Trust has on her.
Three Sales, One Day, March 31
On March 31, 2026, Smith filed three stock sales in a single disclosure. Her full record on Blind Trust shows the lineup: a sale of 3M Company (MMM) in the $50,000 to $100,000 range, a sale of Barnes Group (B) in the $100,000 to $250,000 range, and a sale of Berkshire Hathaway Class B shares (BRK.B) also in the $100,000 to $250,000 range.
A single-day disclosure window covering somewhere between $250,000 and $600,000 worth of stock sold. The midpoint of those ranges puts it around $450,000 out the door on one date.
The three companies don't share an obvious thesis. 3M is an industrial conglomerate with a long litigation shadow. Barnes Group is an aerospace and industrial manufacturer. Berkshire Hathaway is Berkshire Hathaway. You could construct a story about general risk-off sentiment in late March. You could also just note that all three sold on the same day and move on.
The Alpha Record
Blind Trust scores disclosed trades against 30-day excess returns versus the S&P 500. Smith's scored sample covers four trades. She's 0-for-4. Mean 30-day alpha across those four: negative 6.1 percent.
The MMM sale from March 31 clocked in at negative 8.9 percent alpha in the 30 days after the trade — she sold, the stock then outperformed. The HBAN sale from November 2025 came in at negative 1.1 percent. The MRSH sale from January 2026 landed at negative 1.2 percent.
Four trades is not a career's worth of data. A four-trade record doesn't make someone a bad investor. It does make someone whose four disclosed trades all underperformed the market — which is what the filings say.
The One With a Committee Angle
Smith sits on the Senate Committee on Banking, Housing, and Urban Affairs, including its Digital Assets and Economic Policy subcommittees. She also serves on the Senate Finance Committee and the Agriculture Committee.
The Barnes Group (B) sale on March 31 is the one Blind Trust flags for committee overlap. Barnes is categorized under Financial Services jurisdiction in the alpha record. Smith's Banking Committee assignment puts financial-sector holdings in a different category than her 3M or Berkshire trades, which carry no committee overlap.
The Barnes sale ran 30-day alpha of negative 13.4 percent. She sold. The stock subsequently beat the market by 13.4 points over the next month. Worst single-trade alpha in her scored record, and the one tied to her committee jurisdiction.
There are no vote-trade overlaps flagged in the data. The disclosed trade dates don't line up against Senate floor votes in a way that triggers that analysis. The Barnes trade stands on its own: a committee-overlap sale that, on the numbers, went the wrong direction for the seller.
Members are required to disclose. They are not required to divest, recuse, abstain, or explain. That's the system.
The Votes This Week
Smith's recent floor record covers a stretch of votes in May and June 2026. On June 3 she voted Yea on the motion to proceed on a resolution disapproving the EPA's repeal of emission standards for coal and oil-fired power plants — that motion failed. On June 5 she voted Nay on the Secure America Act, which passed.
In May, she voted Yea twice on motions related to directing the removal of U.S. Armed Forces from hostilities against Iran. The first motion, on May 13, was rejected. The second, on May 19, was agreed to.
None of these floor votes sit inside her committee assignments in a way that creates an oversight angle — Banking and Finance committee members vote on EPA rules and Iran war powers the same way every other senator does. Her EPA vote is worth noting on its own terms: she voted to reimpose emission standards on coal and oil-fired plants, the motion lost, and none of her disclosed trades touch the energy sector. The vote and the portfolio don't intersect.
The Biofuels Side Note
Social mentions this week also surface Smith alongside Senator Chuck Grassley touting an S&P Global study on the economic benefits of biofuels for the farming economy. Smith sits on the Agriculture Committee's Rural Development, Energy, and Credit subcommittee — biofuels land squarely in her lane. Nothing in her disclosed trades touches biofuel producers or agricultural commodities in the current 90-day window, so the farming-economy advocacy and the portfolio don't connect.
What the Record Says
Smith's disclosed activity in the last 90 days is a single concentrated sell-off: three sales on March 31, two of them in the $100,000-to-$250,000 band, totaling somewhere north of a quarter million and possibly approaching $600,000 depending on where within those ranges the actual prices fell. All three scored trades from that date moved against her in the 30 days that followed.
The Barnes Group sale is the one the data flags for committee overlap given her Banking Committee assignment. It also carries the worst 30-day alpha in her record at negative 13.4 percent.
The public narrative this week is about a senator introducing postal accountability legislation and showing up for her state party's preferred gubernatorial candidate. The financial record is about a senator whose four disclosed and scored stock trades have all underperformed the market, including a banking-sector sale that cost her roughly 13 points of relative return in a month.
