President Biden visits US-Mexico border

Joe Biden has walked along the US-Mexico border in Texas to see up close one of his presidency's biggest issues.

He visited a migrant centre in El Paso and joined Border Patrol agents in touring a section of the border wall.

The number of migrant crossings has spiralled in recent months, making the Democratic president vulnerable to the accusation he is soft on security.

Last week he announced tougher measures to expand the nationalities of those who can be sent back to Mexico.

But that left the Republican governor of Texas, Greg Abbott, unimpressed - he said the president was failing to enforce immigration laws.
