Pacheco's office and the U.S. embassy in Brasilia did not immediately respond to requests for comment.
Separately, a group of 74 federal lawmakers in the United States and Brazil released a joint statement on Wednesday condemning the political violence in Brasilia and Washington that came two years and two days apart.
The statement, signed mainly by progressive lawmakers in both countries, was articulated by the Washington Brazil Office, a group promoting bilateral dialogue in defense of human rights and sustainable development.
"It is no secret that ultra-right agitators in Brazil and the United States are coordinating efforts," they wrote, citing ties between associates of Trump and Bolsonaro.
The Jan. 6 committee's final report, released last month, said Trump should face criminal charges for inciting the deadly riot.
