A majority of Americans approve of newly empowered House Democrats using their authority to investigate President Donald Trump, but many are worried about possible congressional overreach as a result of the probes, according to a new Washington Post-ABC News poll .

The poll, published Sunday, showed that 57 percent of respondents support Democratic investigations into potential collusion between Trump’s 2016 campaign and Russia; 61 percent support investigations of suspected financial ties between Trump and foreign governments; 59 percent support investigations into Trump’s communications and relationship with Russian President Vladimir Putin; 60 percent support attempts to obtain and release Trump’s tax returns.


However, 46 percent of respondents suspect Democrats will “go too far” in their efforts, while 34 percent think the lawmakers will handle the inquiries “about right.” A majority of respondents, 55 percent, said they do not think Congress should begin impeachment proceedings against the president.

Half of Americans said they have “just some” confidence that special counsel Robert Mueller’s eventual report on Russian interference in the 2016 election and potential coordination between the Trump campaign and the Kremlin “will be fair and even-handed.” Roughly 43 percent reported that they have at least a “good amount” of confidence in the impartiality of Mueller’s final report.

The Post-ABC poll was conducted by telephone from Jan. 21-24 among a random national sample of 1,001 adults, with a 3.5-percentage point margin of sampling error.
