More than two-thirds of Americans believe President Donald Trump's behavior "is not what I expect from a president," according to a poll released in late August.
George Washington University surveyed 1,009 people between Aug. 13 and 17 and found that 71 percent felt Trump's actions were unpresidential, according to Politico.
A majority also feared the commander in chief could start a war, with 68 percent saying Trump's behavior "could get us accidentally involved in an international conflict."
Of respondents, 42 percent approve of the job Trump is doing as president, compared to 55 percent who disapprove. The survey found 56 percent thought he was not an effective president, while 39 percent felt he was.
Trump had a higher favorable rating than both House Speaker Rep. Paul Ryan of Wisconsin and Senate Majority Leader Sen. Mitch McConnell of Kentucky. Forty-one percent viewed Trump favorably, against 36 percent for Ryan and 19 percent for McConnell.
Tensions among the three leading Republicans are running high. Trump tweeted Aug. 24 that McConnell had "failed" in his efforts to repeal the Affordable Care Act, and criticized both McConnell and Ryan for creating the "mess" of the debt ceiling, The Washington Post reported.
The government has enough money to pay its bills until Sept. 29, after which Congress needs to authorize a higher borrowing limit, raising the debt ceiling.
Trump said in a tweet that he asked McConnell and Ryan to attach legislation raising the debt ceiling to a bill on veterans affairs. Trump alleged they refused and "now we have a big deal with Dems holding them up."
Trump reportedly attacked McConnell in a phone call in mid-August.
The White House has not held back from taking on other GOP members.
Asked Aug. 24 about her view of Republican Sen. Bob Corker of Tennessee's suggestion that Trump was incompetent, White House press secretary Sarah Huckabee Sanders issued a sharp rebuke.
"I think that's a ridiculous and outrageous claim and doesn't dignify a response from this podium," she said.
The Washington Post noted that some Republicans who have clashed with Trump have suffered declines in their poll numbers. Sen. Dean Heller of Nevada, who is up for reelection in 2018, refused initially to vote in favor of the GOP health care bill. His approval rating in his own state is at 22 percent.
In Arizona, Sen. Jeff Flake, who has been an outspoken critic of the president, has an approval rating of 18 percent, compared to 61 percent who disapprove.
The George Washington University poll found that 53 percent of Republicans felt their member of Congress had not been supportive enough of the president.
