Staggering Republican report lays out how much is spent on healthcare and accommodation - as they target Mayorkas for impeachment

Taxpayers have to front nearly half a trillion dollars each year because the Biden administration is not stopping migrants at the southern border, Republicans said in a report on Monday.

The cost of providing education, healthcare, law enforcement and other expenditure resulting from millions of extra migrants adds up to as much as $451 billion a year, says the House study.

The 49-page report comes as House Republicans push to impeach Homeland Security Secretary Alejandro Mayorkas for allegedly failing to constrain the record numbers of migrants arriving at the US-Mexico border.

'Every day, millions of American taxpayer dollars are spent on costs directly associated with illegal immigration and the unprecedented crisis at the Southwest border sparked by … Mayorkas' policies,' says the report.
