Richard Milhous Nixon was the 37th President of the United States, serving from January 20, 1969 to August 9, 1974.
In 1972, President Richard Nixon holds a secret, recorded meeting between him and Bolivar Trask. The evidence of this meeting was completely erased from the tapes. After Bolivar Trask is shot dead by Mystique at the Paris Peace Accords in France, he becomes a martyr for the anti-mutant movement, and Nixon uses his death to start a war against mutants by supporting Trask Industries' Sentinels program.

One year later, following the events at the Paris Peace Conference and the attempted assassination of Bolivar Trask by Mystique, live footage of the mutants clashing was broadcast around the world. Trask traveled to Washington D.C. immediately to address the impending threat of mutants with Nixon, to which he asked what countermeasures they could implement against Magneto and Mystique. Nixon then viewed the blueprints for Trask Industries' Sentinels, as fitted with mutant detection devices and made of a non-metallic polymer alloy.
Nixon approves Trask's Sentinel Program and arranged for a public unveiling in Washington, D.C. When the Mark I Sentinels were revealed on the White House lawn, Magneto took control of them and used them to begin attacking Nixon and the other humans in the audience. President Nixon, William Stryker, Bolivar Trask and members of the president's Cabinet took cover in the President's bunker under the White House. Magneto used his powers to pull the entire safe room from the White House and prepared to kill Nixon for approving the creation of the machines designed to eliminate mutants.
Mystique disguises herself as Nixon and comes out of the crowd, in an apparent act of surrender. Whilst Magneto is distracted by Beast and the future Wolverine, Mystique shoots him in the neck and then attempts to assassinate Trask. Thanks to Charles Xavier's telepathic persuasion, Mystique refrains from killing Trask and leaves the scene. After having being saved by a mutant on live television, President Nixon officially shuts down Trask's Sentinel Program and has Bolivar Trask arrested on charges of selling American secrets to their enemies. This action erases a future where the Sentinel program went on to decimate the world and nearly all of mutant and humankind.
