Much of what I told you about this morning on the Early Nightly holds for tonight's broadcast... but a few new developments to fill you in on. Lisa Myers has a number of new details on the terror investigation including an al-Qaida connection. Lisa reports that there is growing evidence the alleged ringleader of the plot had contact with senior al-Qaida leaders. Plus, new video of a key player for this cell in London... and another arrest to report. She will have a full wrap from Scotland Yard.  Also, Pete Williams reports tonight on Homeland Security, with aviation security officials defending the new order that all passengers must remove their shoes.  As you can see... the terror plot still dominating our news coverage. See you tonight.
