Who was the first US persident to travel to communist China and Moscow

Hi there !

The first president Richard M. Nixon

On February 21, 1972, President Richard M. Nixon arrived in China for an official trip. He was the first U.S. president to visit the People's Republic of China since it was established in 1949. This was an important event because the U.S. was seeking to improve relations with a Communist country during the Cold War.

Hope this helps !

The president of the united states does not have the authority to “limit” the power of the judicial branch. however, the president can influence the political direction of decisions made by justices on the supreme court through the nomination process when a position becomes available.i would say the best answer is that he can at least interpret the laws
