Washington: On Friday, US Democrats rolled out their measure aimed at blocking President Donald Trump from circumventing Congress to seize federal dollars for construction of his controversial southern border wall. House Speaker Nancy Pelosi said the chamber will vote next Tuesday on the so-called disapproval resolution to terminate the national emergency that Trump declared last week, an exceptional step that sparked fierce political and legal battles. It is to be noted that the legislation is expected to clear the Democrat-held House of Representatives, then head to the Senate where it is guaranteed a vote under the rules. Its fate, however, is anything but assured in the upper chamber, which is controlled by Trump's Republicans. Trump swiftly weighed in to say he would reject the measure if it reaches his desk, deepening a showdown with his Capitol Hill opponents. also read We will respect the government and the board decision: Virat Kohli on playing against Pakistan in 2019 World Cup Trump said, expressing confidence that Congress would not be able to override his objection "Will I veto it? 100 per cent,". Overriding a presidential veto requires a two-thirds majority in both chambers, meaning substantial numbers of Republicans would have to break with Trump in order for his emergency declaration to be blocked. Pelosi meanwhile hammered away at Trump's "lawless" declaration, saying it had no valid rationale.Pelosi told a conference call Friday from Laredo, Texas, where she and fellow lawmakers were visiting a bridge connecting the US and Mexico "There is no evidence to support the president's false claim of a crisis on the border,". Trump announced the emergency last week in order to bypass Congress, which did not approve the $5.7 billion he wanted for his wall, a longstanding promise from his 2016 presidential campaign. The spending bill, which he reluctantly signed in order to avert a government shutdown, included appropriations of just $1.4 billion for fencing and other barriers along the border, but specifically not for Trump's proposed wall. Democrats -- and some wary Republicans -- condemned Trump's unilateral move as an effort to usurp the powers of the purse, which under the US Constitution are reserved for Congress. "We do not have a monarch, we have a separation of powers in our country," Pelosi said, adding she was urging Republicans to join Democrats in pushing back against the president. also read At ISSF World Cup Indian shooter Apurvi Chandela clinching a gold medal The call to action comes as Trump and the White House press on with plans to repurpose more than $6 billion from other sources, mostly already-allocated funds in the Defense Department budget Trump has repeatedly declared that rampant illegal immigration is fueling a crisis along the border, leading to higher crime and strains on public services such as health care.
