Interest in that meeting has increased, a day after the White House confirmed that the President played a role in crafting the initial misleading statement about the meeting. For weeks Mr. Trump's personal lawyer and the White House denied that the president had anything to do with the statement which was attributed to Donald Trump Jr. There was also no effort apparent effort to correct the record.

On Capitol Hill, a once-outspoken Republican defender of Mr. Trump is sounding more like a critic.

When he was asked to respond to the new revelations about the president's role in producing the statement and about the Trump Tower meeting itself, Idaho Senator James Risch said, "I guarantee you there were phone calls in addition to those emails, and I want to hear all of it before I answer the question you put to me."

Risch serves on the Senate Intelligence Committee which has an ongoing investigation mirroring the probe underway by the House Intelligence Committee.
