The Tyler and Polk administrations
Both administrations strongly supported American westward expansion.
John Tyler pressed for the annexation of Texas as a slave state during his administration (1841-45) and at the end of it, he signed a Texas annexation bill into law, which was admitted as a state in the first year of Polk's presidency.
James K. Polk, who ruled from 1845 to 1849, also supported American expansion to the point he led the U.S. into the Mexican-American War (1846-48) in which the U.S. gained what is today California and much of the present-day Southwest.
One of the messages being portrayed through touch is a message of comfort. The women in the blue shirt has a gentle hand laid on the women crying, and this is a way of comforting the woman in the pink shirt. The woman in the pink shirt is also communicating that she needs/wants comforting by leaning into the woman in the blue shirt. I hope that helps!
President Richard Nixon did all of these things except be impeached. Instead, as a result of the Watergate scandal, he resigned while still in office. Many think he would have been impeached had he remained in office.
