Trump says he's most hounded leader ever

WASHINGTON -- Brimming with resentment, President Donald Trump fervently denied Thursday his campaign had collaborated with Russia or he'd tried to kill an FBI probe of the issue, contending "even my enemies" recognize his innocence and declaring himself the most unfairly hounded president in history.

Asked point-blank whether he'd done anything that might merit prosecution or even impeachment, he said no and then added concerning the allegations and questions that have mounted as he nears the four-month mark of his presidency: "I think it's totally ridiculous. Everybody thinks so."

Not quite everybody.

While Trump tweeted and voiced his indignation at the White House, deputy attorney general Rod Rosenstein, who appointed an independent special counsel to lead a heightened federal Trump-Russia investigation the day before, briefed the entire Senate behind closed doors at the Capitol.

By several senators' accounts, he contradicted Trump's statements Rosenstein's written criticism of former FBI director James Comey had been a factor in Comey's recent firing by the president.

Trump is leaving today for his first foreign trip, to the Mideast and beyond, and aides had hoped the disarray at home would have been calmed if not resolved, allowing the White House to refocus and move ahead.

Republicans on Capitol Hill hoped the same, reasoning the appointment of a special counsel could free them to work on a major tax overhaul and other matters without constant distractions.

Trump said he was about to name a replacement for Comey, another move to settle the waters. Former Connecticut senator Joe Lieberman was seen as the frontrunner.

But calm seemed far off.

Trump clearly knew what he wanted to say as he took a few questions at a news briefing with visiting Colombian President Juan Manuel Santos.

Did he urge Comey at a February meeting to drop his probe of the Russia connections of Trump's former national-security adviser, Michael Flynn?

"No. No. Next question."

Did he collude with Russia in his campaign to defeat Democrat Hillary Clinton?

"Everybody, even my enemies, have said there is no collusion," he maintained.

Another answer on that subject seemed both more specific and perhaps ambiguous, however.

"There is no collusion between certainly myself and my campaign -- but I can only speak for myself -- and the Russians. Zero."

"The entire thing has been a witch hunt," he declared, echoing one of the tweets he'd sent out just after dawn: "This is the single greatest witch hunt of a politician in American history!"

He said he respected the special-counsel appointment but also said it "hurts our country terribly."

At the other end of Pennsylvania Avenue, Rosenstein was briefing the Senate about his decision to appoint former FBI director Robert Mueller to lead the independent Trump-Russia probe.

Senators said Rosenstein steered clear of specifics while making clear Mueller has wide latitude to pursue the investigation wherever it leads, including potential criminal charges.

Despite the president's furious reaction, some fellow Republicans welcomed Mueller's appointment and expressed hope it would restore some composure to a capital plunged in chaos.

"We'll get rid of the smoke and see where the actual issues lie," said Sen. Tim Scott, R-S.C.

"I do think that the special prosecutor provides a sense of calm and confidence perhaps for the American people, which is incredibly important."
