Which US President famously called for “Mr. Gorbachev, tear down this wall” regarding the Berlin Wall?

The phrase "Mr. Gorbachev, tear down this wall" was famously spoken by President Ronald Reagan during a speech delivered on June 12, 1987, in West Berlin. This statement was directed at the General Secretary of the Soviet Union, Mikhail Gorbachev, and was a powerful call for the dismantling of the Berlin Wall, which had divided East and West Berlin since its construction in 1961. Reagan's speech was significant not only as a moment of oratory but also as a reflection of the Cold War tensions and the desire for greater freedom and reform in Eastern Europe. This moment is often seen as a pivotal point in the eventual fall of the Berlin Wall in 1989 and the broader collapse of communist regimes in Eastern Europe. The other presidents listed did not make this particular statement or have the same direct call to action regarding the Berlin Wall during their time in office.
