The US Senate passed on Saturday President Joe Biden's much-awaited $1.9 trillion COVID-19 relief bill, sending it back to the House of Representatives for approval.

Axar.az reports that the upper chamber had a 50-49 vote, with one absentee and all Republicans voting against the relief package, which was passed through budget reconciliation - a process that required every Democratic vote without any Republican support.

While Republicans are worried about too much liquidity injected into the economy, Democrats argue that an extensive package is needed for quick recovery in the world's largest economy.

"The Senate has never spent $2 trillion in a more haphazard or less rigorous way," Senate Minority Leader Mitch McConnell wrote on Twitter, reminding that Congress passed last year five pandemic rescue packages totaling $4 trillion.

"Instead of working together to fight COVID-19, Democrats decided to exploit the crisis by jamming through unrelated liberal policies they couldn’t pass honestly," the Republican lawmaker of Kentucky added.
