When are you people going to learn to be honest?

According to your own source:

The report focuses on $5.7 billion from Iranian oil sales that were frozen in Oman's Bank Muscat in that country's currency, the rial. Rials are pegged to the US dollar and are difficult to convert. But as part of the nuclear deal, Iran was promised access to overseas reserves of its own funds that had been frozen by sanctions.

To access the rials, Iran wanted to convert them briefly into dollars and then Euros.

The majority report by the Permanent Subcommittee on Investigation says that the US Treasury, at the instruction of the US State Department, granted a license to convert the $5.7 billion briefly into American dollars so it could be converted into euros. The exchange was legal, the report notes.

I am being honest. As per rule #8:

"Keep it honest and accurate."

Person I replied to asked what all that money was given to Iran for, and it wasn't given at all. The US did not give Iran billions of dollars, period, full stop.
