NEW YORK — Rudy Giuliani, President Donald Trump’s personal attorney, said Tuesday that the president asked him to brief the Justice Department and Republican senators on the findings of his recent trip to Ukraine.

Giuliani indicated he would aim to do so by week’s end but did not provide details. He would not discuss the contents of his findings.

Giuliani’s trip last week prompted concern from many White House officials, some of whom blame the lawyer for ensnaring Trump in the Ukraine affair that has led to articles of impeachment.

Even as impeachment swirled, Giuliani stunned Washington by traveling to Ukraine this month to further his probe. The surprise journey drew condemnation from Democrats and some scorn from Republicans and White House aides, many of whom believed the sojourn to Kiev drew unwanted scrutiny ahead of the impeachment vote. Trump, though, appeared to praise the trip when talking to reporters in recent days.

“He says he has a lot of good information,” Trump said Saturday. “I hear he has found plenty.”
