The core claim is well supported by Current Federal Debt and Deficit, which reports a March FY26 federal deficit of $164 billion versus $161 billion in March FY25, consistent with a roughly 2% year-over-year increase. Deficit Tracker independently corroborates both the $164 billion reported monthly deficit and the timing-adjusted figure of $249 billion, which aligns with the user's rounded '$250 billion.' The weaker part of the claim is that the figure exceeded a $153 billion expectation: none of the fetched sources are primary Treasury releases or market expectation data, so that specific comparison is not directly validated here. Still, the main numerical statement about the March deficit and the timing adjustment is supported.
