About 30 minutes into his rally, Trump said he had been challenged by "a young man who's got very little going for himself except he's got a great first name".
But it also had something extra. "Although last year's breakdown was over funding for Trump's border wall, the impasse this week concerned bed space for detained undocumented immigrants".
O'Rourke, whose unexpectedly close but ultimately unsuccessful campaign for U.S. Senate generated buzz about a 2020 presidential bid, said last week he will decide by the end of the month whether to run.
