From Fox News:
"The process of releasing the memo could take up to 19 congressional working days which puts its release around mid-March. The document’s release would first need approval from House Intelligence Committee Chairman Devin Nunes, R-Calif., who can decide to bring the committee back together for a vote. If the majority of the committee votes to release the memo, it would then be up to President Trump. If he says yes, the memo can be released.
Sooo – the committee voted to release it on Monday. Now today it looks like Trump signed it. Where does the 19 days come in?
