AUSTIN - Gov. Rick Perry is again visiting the Texas-Mexico border as he continues to hammer President Barack Obama for failing to do so.
Perry tweeted Thursday that he was in the Rio Grande Valley, including pictures of himself near a helicopter and at a border security meeting in Weslaco.
His office didn't return messages seeking more information.
Perry has criticized Obama for failing to come to the border amid a flood of unaccompanied immigrant children crossing into Texas. The governor has now been there three times since the issue began drawing national attention.
Obama discussed the border with Perry in Dallas on Wednesday, and spoke about the economy in Austin on Thursday.
But Obama has resisted calls from Republicans and some Texas Democrats to get a first-hand look at the border.
