I can't make sense of why President Trump wanted a border wall between USA and Mexico. Was it really needed?

President Trump wanted to build a border wall between the United States and Mexico because he believed it would help stop illegal immigration and drugs from entering the country. He claimed that the Wall would reduce crime and make the US more secure. Critics argued that the Wall wasn't needed, as there is already a lot of physical barriers and laws in place to deter illegal crossings.
