Some things never change, like US government interference in the political processes of other countries.
The woman in the picture is Lilian Tintori, celebrity wife of Leopoldo Lopez, who is in jail in Venezuela for organizing violent anti government protests that killed at least 40 people including several police officers.
Lopez currently is the public face of the old oligarchy that used to run Venezuela and that with US government organizational and monetary assistance -- some secretly through the CIA and some overt and open via US state department agencies like USAID -- has been trying to topple elected Socialist governments of Venezuela by various means ever since Hugo Chavez was first elected president in 1998 -- an effort taken up by Barak Obama and his secretaries of state Hillary Clinton and John Kerry and shamefully by New Mexico's federal delegation with their votes and by repeating misinformation about Venezuela.
Now that Lopez is in prison Tintori fronts the Venezuelan opposition, and Trump is giving the full oval office photo-op presidential backing to this symbol of US meddling in the internal affairs of other countries even as the US political class and its media megaphones squeal about interference in US elections (and infiltration of the Trump government) by Russia, for which -- one more time -- no evidence has been put forth, a crucial fact now and then conceded by the mainstream media even as it whips up anti Russia frenzy day in and day out.
Update 2/16/17 8:52 pm: Venezuela Analysis, an independent outlet generally supportive of Venezuelan Socialism, has posted an article about Tintori's White House visit.
