US House Speaker Kevin McCarthy said on Saturday that he was directing relevant committees to investigate whether federal funds are being used to interfere in elections by what he described as a politically motivated prosecution of former President Donald Trump.
"An outrageous abuse of power by a radical DA," McCarthy said in a tweet, without naming the district attorney.
Earlier on Saturday, Trump said he expected to be arrested on Tuesday as the Manhattan district attorney's office considers charges over a hush money payment to a porn star.
