The sales of CSX and Zoetis were the senator's entire positions in the stock. Mullin recently disclosed selling multiple other stocks during the month of November with his lone purchase in his last disclosure being a $250,000 to $500,000 buy of Microsoft Corporation (NASDAQ:MSFT) stock.

Mullin's Trades Catch Attention
As a close ally of Trump and a member of several Senate committees, the trading activity of Mullin has been more closely watched by retail investors in recent months.
Benzinga has previously flagged the senator for questionable disclosures.
Earlier this year, Mullin violated the STOCK Act by reporting transactions he made in 2023 two years later in 2025.
Mullin serves on the Committee on Appropriations, Committee on Armed Services, Committee on Indian Affairs and the Committee on Health, Education, Labor and Pensions. He also serves on various subcommittees. The role of the Armed Services committee has been closely followed, with trades in defense stocks or companies that could benefit from war, raising potential conflicts of interest.
The recent purchases of Microsoft, Pentair, and Capital One Financial will be closely monitored to see if they end up with new government contracts or gain favor with the president going forward.
