The May US deficit came in at $135.9 billion, the third highest (or, technically, lowest) May on record, but better than last May's $189.7 billion. This number was made up of total outlays of $282.7 billion and receipts of $146.8 billion, 3rd and 4th highest ever, respectively. Sequentially, the number was $53 billion worse than the April deficit of $82.7 billion. Total interest on Treasury debt was $23.8 billion, or 8% of total outlays. Surprisingly, in May, the DTS announced that only $43 billion of new debt was raised (largely due to a settlement delay of about $100 billion at the end of May which hit the June ledger).

Below is a chart of historical outlays, receipts and total deficits.

And a breakdown of the individual receipt and outlay components:
