During a campaign appearance in Billings, Montana, Trump also praised Greg Gianforte, the Republican congressman who physically attacked the Guardian reporter Ben Jacobs previous year, as "a fighter and a winner". "It doesn't help the president". And someday, when I'm not president.
Ryan has been an occasional critic of the president's, and the two clash on issues like tariffs, Russian Federation and immigration.
Mr Trump said he won't be settling for that response. "And guess what, we are passing good laws that improve people's lives".
They did all that work, only to reveal findings that are glaringly obvious: The op-ed was likely written by, wait for it - an older, conservative male.
He also said the Times should publish the author's identity "for the sake of our national security".

The op-ed described Trump's leadership style as "impetuous, adversarial, petty and ineffective".
But the internet and Trump's own aides were abuzz with speculation over who the unnamed official might be and whether the act of defiance was tantamount to a coup in the making. I guess by process of elimination, it will probably come down to the butler. We are focusing on the well-being, the kitchen table, the concerns of America's working families.
Trump and his inner circle have been in damage control all week fighting similarly themed revelations contained in Pulitzer Prize-winning journalist Bob Woodward's upcoming book, "Fear: Trump in the White House".
White House press secretary Sarah Sanders, in a separate statement, called the anonymous author a "coward" who should resign.
Trump later tweeted, "TREASON?" and in an extraordinary move demanded that if "the GUTLESS anonymous person does indeed exist, the Times must, for national security purposes, turn him/her over to government at once!"
