Rep. Schiff says Republicans have been boycotting House Intel Committee briefings. "We’ve had important briefings on national security issues … and for whatever reason they’ve decided en masse they’re not going to attend."
This - FINALLY - is the point. Very, very clear that the White House finally released the aid only when the whistleblower report was coming to light and the Intel committee was already starting its investigation! They relented because they finally got caught.
