First pardoned Jan. 6 rioters released in DC

Trump signed several other executive orders before the cheering crowd, including ones freezing federal hiring except for the military and other excluded categories; requiring federal workers to return to full-time, in-person work immediately; restoring the freedom of speech; and directing every federal department to address inflation.

The last order he signed in the arena directs the federal government to end the "weaponization of government against the political adversaries of the previous administration."

Trump tossed several pens into the crowd before leaving to head back to the Oval Office to sign more executive orders.

Trump also signed an order withdrawing the United States from the Paris Agreement.

The agreement was originally ratified at the annual United Nations Climate Conference in 2015. It intended to limit global warming to 1.5 degrees Celsius, compared to pre-industrial levels -- a metric scientists believed would significantly reduce the impacts of climate change.

During his first term in office, Trump withdrew from the agreement; Biden re-entered it on his first day in office.

Following his remarks, Trump sat down at a desk in the Capital One Arena to sign what he previewed as a wide range of executive orders.

The first order rescinded 78 Biden-era executive actions, executive orders, presidential memoranda and others.

The crowd booed loudly when Trump brought up Joe Biden's last-minute pardons for members of his family.

"Did you know that Biden, while I was making my speech, pardoned his whole family? The brother. The whole deal was pardoned. Can you imagine that?" Trump said.
