WASHINGTON (Reuters) - U.S. President Joe Biden plans to sign his signature $1.9 trillion coronavirus relief package on Friday, White House press secretary Jen Psaki said on Wednesday. The comments came ahead of the expected final passage of the measure in U.S. House of Representatives on Wednesday. The White House is moving “full speed ahead” on the implementation of the bill, which includes $1,400 checks for most Americans, Psaki said.
