The Obama emergencies included the Swine Flu, Flint water crisis and Iran.
Congress believes President Trump has $21 billion in unobligated military construction funding money available for the border wall with Mexico.
Foreign Policy reported:
The announcement Thursday that U.S. President Donald Trump plans to declare a national emergency over the southern border is very likely to rope in the Pentagon, as the White House seeks to divert military funds to build his long-promised wall on the U.S.-Mexico border.
Congress believes the Pentagon has $21 billion in unobligated military construction funding—money that has been appropriated by the legislature and set aside for specific projects but not yet issued—that the president could use to build the wall over objections from Congress, according to two congressional aides.
