WASHINGTON — The United States says Venezuelan President Nicolas Maduro's accusation that Vice President Joe Biden conspired against him is "patently false."

Maduro claimed in a televised address that Biden sought to foment the overthrow of his socialist government during a Caribbean energy summit Biden hosted last month. Maduro says Biden told Caribbean heads of state that the Venezuelan government's days were numbered and it was time they abandon their support.

Maduro says what Biden did "has no name."

The White House is hitting back. In a statement, the vice president's office says Maduro is trying to distract from concerning conditions in Venezuela, including repeated violations of personal freedoms and due process.

The clash comes one month after Biden and Maduro chatted briefly in Brazil and expressed a desire for restored ties.
