As a measure of how politically fraught President Barack Obama's Texas trip is Wednesday, Republican Gov. Rick Perry reluctantly agreed to a ritual public greeting of the nation's chief executive.

The White House said Perry will welcome the president when he lands in Texas for a meeting with local civic and religious leaders about the influx of tens of thousands of migrant children along the southern U.S. border, before Obama heads to fundraisers for Democratic congressional campaigns.

The governor, who has accused the president of not caring "whether or not the border of the United States is secure," will join Obama for the border meeting.
