Chavez brought up Robertson's remarks while addressing supporters at the presidential palace, saying "he has expressed the desire of the elite that governs the United States."
"If something happens to me, the responsible one will be George W. Bush," said Chavez, who has repeatedly accused the Bush administration of plotting to overthrow him.
The United States has repeatedly denied having any intentions to try to topple Chavez or harm him.
Chavez's comments were his sharpest since Robertson called for his assassination Monday on his TV show "The 700 Club," saying the United States should "take him out" because Chavez poses a danger to the region.
Robertson later issued an apology, saying he spoke out of frustration. U.S. State Department spokesman Sean McCormack on Tuesday called Robertson's remarks "inappropriate," but stopped short of condemning them.***
Roughly 1,000 demonstrators were marching through the capital to demand that officials on the National Election Council, which is seen as pro-Chávez by government opponents, are replaced before upcoming congressional elections.
Six people were injured when alleged Chávez supporters attacked the march, launching fireworks and throwing glass bottles, rocks and tear gas canisters, Caracas Fire Chief Delio Martínez said.
The violence broke up the march several blocks from congress. The injured were taken to nearby hospitals, the Globovisión television news channel reported.
''This government is all about lies,'' said Rómulo Zambrano, a 50-year old publicist, as he marched toward the National Assembly in downtown Caracas. ...........***
