Mr Trump has taken to Twitter to repeatedly rebuke the Democrats for not contributing to the security of the US southern border:
Sad when you think about it, but Mexico right now is doing more for the United States at the Border than the Democrats in Congress! @foxandfriends— Donald J. Trump (@realDonaldTrump) 11 июня 2019 г.
On Monday, House Democrats lost the first round of their legal battle against Trump’s plan to spend billions of dollars in federal funds to pay for a wall on the border with Mexico. Originally, Congress designated $1.375 billion for the construction of the border barrier, but Trump wanted an additional $2.5 billion from the Department of Defence counter-drug efforts, $600 million from the Treasury Forfeiture Fund, and $3.6 billion in military construction funds. Democrats insist that since Congress refused to give the administration the money President Trump wanted to pay for the wall, his plan to use additional sources violates the Constitution's Appropriations Clause and some other federal laws.
Last week, the US and Mexico issued a joint bilateral declaration on measures to reduce the flow of illegal migrants through the US-Mexican border. Mexico has agreed to send its National Guard to the southern border and take steps to stop human smuggling. The US, for its part, will return asylum seekers trying to cross the border to Mexico, where they will remain as their cases are decided on.
The so-called 'migrant caravan' from Central America began making its way to the US through Mexico in the autumn of 2018. In February, Mr Trump declared a national emergency over the migrant situation in order to raise up to $8 billion in federal funds for the construction of his much-debated border wall.
