on july 20, 2007, cnbc replaced the first hour of the two-hour program with an expanded "squawk on the street", due in part to claman's departure from the network (which she joined fox news channel's sister network financial unit three months later). dylan ratigan and trish regan served as interim anchors for the program, which was completely revamped on 2007-07-23. in addition to the aforementioned 2007-07-23 revamp, the anchors were joined on set by a guest contributor, very similar to "squawk box".
