In Michigan, Representative Fred Upton told an audience at the Detroit Economic Club that while he did not support an impeachment inquiry, “there are legitimate questions” about Mr. Trump’s interactions with Ukraine, and he had no problem with Democrats’ efforts to get more information.
“We need to know what the answers are,” he said.
In Texas, Representative Will Hurd — who is retiring, and therefore perhaps feeling liberated to speak his mind — has called on the House to investigate the “troubling” allegations against Mr. Trump, though he cautioned against a rush to impeachment. In Pennsylvania, Representative Brian Fitzpatrick said he thinks law enforcement should investigate. In Illinois, Representative Adam Kinzinger said, “I want to know what happened here.”
In Maine, Senator Susan Collins, a Republican whose seat is seen by Democrats as especially vulnerable, also criticized Mr. Trump’s decision to call on China to investigate a political rival. “It’s completely inappropriate,” she told the Bangor Daily News on Saturday.
And in Utah, Senator Mitt Romney, who has emerged as a lonely voice criticizing Mr. Trump’s dealings with Ukraine, and last week called the president’s appeal for foreign help investigating the Bidens “wrong and appalling,” appears to have company. Before a whistle-blower’s complaint against Mr. Trump was made public, a fellow Utahan, Representative John Curtis, introduced a resolution calling for the White House to release it, and he has said he is “closely monitoring the formal inquiry.”
On Saturday, in a warning shot to Republicans who might cross him, Mr. Trump lashed out at Mr. Romney on Twitter, calling him a “pompous ‘ass’ who has been fighting me from the beginning” and using the hashtag #IMPEACHMITTROMNEY.”
