Venezuela's opposition leader returned to his country Monday, putting himself at risk of arrest.  Juan Guaidó flew into Caracas where he was welcomed back by crowds of supporters.

Guaidó spent the past few days traveling to regional South American neighbors, including Colombia and Ecuador.

He violated a travel ban when he left Venezuela, and international watchers didn't know what would happen when he tried to return.  Guaidó declared himself Venezuela's interim president, and he's received  wide support  from other countries, including the U.S. But current president Nicolás Maduro refuses to relinquish power.

He was sworn in for a second term earlier this year, despite accusations that it was a fraudulent election.

Guaidó  tweeted after the rally Monday  that there's a lot of work the country needs to do, and there's nothing to celebrate just yet.

He called on the country to mobilize again on Saturday.  Additional reporting from  Newsy affiliate CNN .
