The article says Congress was blocking the transfer. Also, other articles on this topic emphasize that this was done in defiance of Congress.
The funds were made available legally by the appropriation process as part of the continuing resolution to fund the government through April 28, 2017.
There has been no Congressional action enforceable that blocks these funds to be delivered to the Palestinians as Congress approved of them. Some holds were placed by members of Congress, but these are non-binding.
Sorta like giving your kid a twenty and telling him to go down and get an extra large pizza, then getting mad when he actually spent it on what you told him to do.
Our wonderful Congress led by the fool Paul Ryan is the culprit here, as all Obama did was to do what the Executive was instructed to do by Congress in the appropriation.
It is a travesty that some think Obama was the cause of this action, but in reality Congress caused it to happen.
The question to ask your congressman is, why, when we are over $18 trillion in debt, we should sink deeper in order to ensure the Palestinians get more of our money to hate us.
