White House cites an old law
The White House held up an article published in the conservative-leaning Washington Times in 2010 as support for Trumps statement.
. . .
Theres a problem with citing this nearly eight-year-old article, however: The 2000 law has largely been superseded by a law enacted in 2011.
Notably, the 2011 measure decriminalized the act of entering the country without documentation and allowed undocumented immigrants to use education and health services. It also set criminal penalties for abuse of migrants by immigration agents.
. . .
While Mexico has taken a variety of measures to limit illegal immigration and asylum for Central Americans, specialists have deemed efforts on Mexicos southern border to be largely unsuccessful.
"Mexico's borders are quite porous," said Wolf of the Mexican think tank. "There are many areas where people and goods can pass through fairly easily, and there is little that the migration authorities or the security forces could do about that."
. . .
Our ruling
Trump tweeted that Mexico has "very strong border laws ours are pathetic."
Broadly, Mexico does admit fewer immigrants than the United States. But the strict Mexican law cited by the White House as evidence has largely been supplanted by a softer 2011 law. In addition, Trump underplays the increasing robustness of U.S. immigration laws and enforcement even under his predecessors, while downplaying how porous Mexicos own southern border is.
We rate the statement Mostly False.
