Pence will hold bilateral talks with Temer and other Brazilian officials on Tuesday. On Wednesday he is scheduled to visit an Amazon jungle city where refugees from Venezuela are being housed. He will travel to Ecuador Wednesday afternoon.

Temer "will express his worries about the treatment" of about 50 Brazilian children who were separated from their parents as part of the Trump administration's policy of seeking to detain and prosecute anyone accused of entering the country illegally, said Brazilian diplomat Fernando Magalhaes during a Monday foreign ministry briefing in Brasilia.

In an about-face last week, US President Donald Trump issued an executive order that ended the separations at the US-Mexico border, but reuniting children with parents has proven troublesome.
