Trump confronts the limits of impeachment defense strategy

WASHINGTON — President Donald Trump is confronting the limits of his main impeachment defense.

As the probe hits the one-month mark, Trump and his aides have largely ignored the details of the Ukraine allegations against him. Instead, they’re loudly objecting to the House Democrats’ investigation process, using that as justification for ordering administration officials not to cooperate and complaining about what they deem prejudicial, even unconstitutional, secrecy.

But as a near-daily drip of derogatory evidence emerges from closed-door testimony on Capitol Hill, the White House assertion that the proceedings are unfair is proving to be a less-than-compelling counter to the mounting threat to Trump’s presidency. Some senior officials have complied with congressional subpoenas to assist House Democratic investigators, defying White House orders.

Asked about criticism that the White House lacks a coordinated pushback effort and could do a better job delivering its message, spokeswoman Stephanie Grisham said, “It’s hard to message anything that’s going on behind closed doors and in secret.”

“It’s like you’re fighting a ghost, you’re fighting against the air. So we’re doing the best we can,” she said on Fox News.

It was a rare public admission from the White House that despite the president’s bravado, real risks remain.

White House officials, who have been treating unified Republican support for Trump as a given, have grown increasingly fearful of GOP defections in a House impeachment vote and a potential Senate trial. While they do not believe there will be enough votes to remove the president, as Democrats hope, the West Wing believes more must be done to shore up Republican support to avoid embarrassment and genuine political peril.

Trump himself has been upset with his own top aides — including Grisham and acting chief of staff Mick Mulvaney — for not sufficiently changing the story line. Instead he relies on his Twitter account and Q&A sessions with reporters to launch daily attacks on the probe. And while Trump’s personal lawyer, Rudy Giuliani, has added to the smoke screen, much as he did during the Russia probe, the former New York City mayor has dramatically scaled back his media appearances since several of his associates were arrested in connection with Ukraine.
