Given the reference text about the American Rescue Plan Act, tell me how much money was authorized to be spent.

The American Rescue Plan Act of 2021, also called the COVID-19 Stimulus Package or American Rescue Plan, is a US$1.9 trillion economic stimulus bill passed by the 117th United States Congress and signed into law by President Joe Biden on March 11, 2021, to speed up the country's recovery from the economic and health effects of the COVID-19 pandemic and the ongoing recession.[1] First proposed on January 14, 2021, the package builds upon many of the measures in the CARES Act from March 2020 and in the Consolidated Appropriations Act, 2021, from December.[2][3]

Beginning on February 2, 2021, Democrats in the United States Senate started to open debates on a budget resolution that would allow them to pass the stimulus package through the process of reconciliation which would not require support from Republicans. The House of Representatives voted 218–212 to approve its version of the budget resolution. A so-called vote-a-rama[4] session started two days later after the resolution was approved, and the Senate introduced amendments in the relief package. The day after, Vice President Kamala Harris cast her first tie-breaking vote as vice president in order to give the Senate's approval to start the reconciliation process, with the House following suit by voting 219–209 to agree to the Senate version of the resolution.

On February 8, 2021, the Financial Services and Education and Labor committees released a draft of $1.9 trillion stimulus legislation. A portion of the relief package was approved by the House Ways and Means on February 11, setting it up for a vote in the House. The legislation was also approved by the Transportation and Infrastructure, Small Business, and House Veterans Affairs committees. On February 22, the House Budget Committee voted 19–16 to advance the bill to the House for a floor vote.[5] The bill passed the House by a vote of 219–212 on February 27. All but two Democrats voted for the bill and all Republicans voted against the bill.[6] A modified version passed the Senate on March 6 by a vote of 50–49.[7] The final amended bill was passed by the House on March 10 by a vote of 220–211 with one Democrat voting against it with all Republicans.[8] The bill was signed into law by President Biden on March 11, 2021,[9] which was the first anniversary of COVID-19 being declared a pandemic by the World Health Organization.

The American Rescue Plan authorized $1.9T of economic stimulus to be spent.
