The US Supreme Court has allowed President Donald Trump to use 2.5 billion dollar of Pentagon funds for building sections of a border wall with Mexico. <br />'' <br />'' The court ruled by five votes to four to block a ruling by a federal judge in California that barred the President from spending the money on the wall.<br />'' <br />'' The wall, dividing the United States and Mexico, was Mr Trump's major campaign promise during the 2016 election. He tweeted after the announcement that it is a big victory for Border Security and the Rule of Law. <br />'' <br />'' The decision by the Supreme Court means that the money will be used for wall projects in California, Arizona and New Mexico.<br />'' <br />'' The President has argued that a new wall would help to curb illegal immigration, which he says is fuelling crime and placing a strain on the economy.<br />'' <br />'' Donald Trump declared an emergency earlier this year, saying he needed 6.7 billion dollar to build the wall as a matter of national security. He ended the shutdown in February after the Congress gave him approximately 1.4 billion dollars in border wall funding. <br />''
