President Donald Trump’s vows to roll out punishing new tariffs on Aug. 1 have barely made a ripple with investors who are convinced he’ll once again back down. But at the White House, officials insist they’re serious this time.

U.S. stocks advanced and the dollar firmed on Friday as investors girded themselves for the week ahead, which includes a Federal Reserve policy meeting, crucial corporate results and U.S. President Donald Trump's August 1 deadline for negotiating trade deals.

The president sued the publication last week, accusing it of defamation for an article about his ties to the disgraced former financier Jeffrey Epstein.

The libel suit, which seeks at least $10 billion in damages, was filed the same day the Justice Department asked a judge to unseal grand jury transcripts tied to Jeffrey Epstein's case.

Trump's legal case against the Wall Street Journal over a story about the president and Jeffrey Epstein could face hurdles, one of which is that it does not appear to comply with Florida state rules over the timing of defamation lawsuits.

A judge grants the paper's request for a deadline extension and sealing of records in Donald Trump's $10 billion defamation suit, citing privacy concerns.
