British Ambassador Sir Peter Westmacott and House Intelligence Committee Chair Rep. Mike Rogers (R-Mich.) spoke about the latest in the investigation into who killed Foley and the threat that the Islamic State poses to the United States, Europe and the Middle East.

The situation in Ferguson, Mo., also was discussed on the major networks. Missouri Gov. Jay Nixon (D) took to the airways to discuss the situation in Ferguson, where Attorney General Eric Holder traveled this week to meet with community leaders. Holder also met with the family of Michael Brown, an unarmed black teenager who was shot and killed by police on Aug. 9. Violent clashes between protesters and police broke out after Brown's death. Things took a more peaceful turn this week. Brown will be buried Monday.
