====Taft Mexican Summit (1909)====
In 1909, President [[William H. Taft]] agreed to meet with Mexican president [[Porfirio Díaz]] in [[El Paso, Texas]], and [[Ciudad Juárez, Chihuahua]], the first meeting between a U.S. and a Mexican president and also the first time an American president visited Mexico.{{sfn|Harris|Sadler|2009|pp=1–2}} The historic summit resulted in serious assassination threats and other security concerns for the nascent Secret Service, so the [[Texas Ranger Division|Texas Rangers]], 4,000 U.S. and Mexican troops, [[Bureau of Investigation|BOI]] agents, U.S. Marshals, and an additional 250-man private security detail led by [[Frederick Russell Burnham]], the celebrated scout, were all called in by Chief [[John Wilkie]] to provide added security.{{sfn|Harris|Sadler|2009|p=15}}<ref>{{cite news |date=October 16, 1909|title=Mr. Taft's Peril; Reported Plot to Kill Two Presidents|newspaper=Daily Mail |location=London |issn=0307-7578}}</ref> On October 16, the day of the summit, Burnham discovered a man holding a concealed [[Protector Palm Pistol|palm pistol]] standing at the El Paso Chamber of Commerce building along the procession route.<ref>{{harvp|Hammond|1935|pp=565–566}}</ref> The man was captured and disarmed only a few feet from Díaz and Taft.{{sfn|Harris|Sadler|2009|p=213}}
