LaRouche founded the Worldwide LaRouche Youth Movement (WLYM) in 2000, saying in 2004 that it had hundreds of members in the U.S. and a lesser number overseas.
During the Democratic primaries in June 2000, he received 53,280 votes, or 22 percent of the total, in Arkansas.

In 2002 LaRouche's Executive Intelligence Review argued that the September 11, 2001 attacks had been an "inside job" and "attempted coup d'etat", and that Iran was the first country to question it.
The article received wide coverage in Iran, and was cited by senior Iranian government officials, including Akbar Hashemi Rafsanjani and Hassan Rouhani.
Mahmoud Alinejad wrote that, in a subsequent telephone interview with the Voice of the Islamic Republic of Iran, LaRouche said the attacks had been organized by rogue elements inside the U.S., aiming to use the incident to promote a war against Islam, and that Israel was a dictatorial regime prepared to commit Nazi-style crimes against the Palestinians.

In 2003 LaRouche was living in a "heavily guarded" rented house in Round Hill, Loudoun County, Virginia.

LaRouche again entered the primary elections for the Democratic Party's nomination in 2004, setting a record for the number of consecutive presidential campaigns; Democratic Party officials distanced themselves from him and did not allow him to participate in candidate forum debates.
He did not run in 2008.

As during the preceding decade, LaRouche and his followers denied that human civilization had harmed the environment through DDT, chlorofluorocarbons, or carbon dioxide.
According to Chip Berlet, "Pro-LaRouche publications have been at the forefront of denying the reality of global warming".
