Richard Nixon, the 37th President of the United States, addressed the nation 40 years ago today and announced his resignation. He officially left office at noon the next day. Nixon was flying over Missouri when Gerald Ford took his oath of office.
On 8 September 1974, President Ford addressed the nation (see video below). These images show the moment when Ford signed proclamation 4311 which gave Nixon a full and unconditional pardon from crimes committed related to the Watergate Scandal or any other crime committed while in office as U.S. President.
Although this photo above is of lower resolution, you can note that Ford's jaw is clenched and the muscles covering the front of his chin are contracted and dimpled (1:24 in the video below). Moreover, his "mustache area" (between the upper lip and nose) is tightened. Simultaneous nasal flaring is also present.
Had Ford's jaw not been clenched - his lips - which are partially rolling inwards (ergo a truncated "Inward Lip Roll") would have been fully expressed. Because of his jaw clenching however, his Inward Lip Roll (ILR) could not form in its entirety. The "Peri-Lip Bulge" which can be seen below Ford's lower lip is essentially only seen in the presence of a clenched jaw.
The nonverbal cluster context displayed here - tells us that President Ford was both angry as well as trying to suppress both this outward display and the inward crescendo of his anger.
