Among 11 topics polled in the Nov. 2-4 survey, which carries a 2-percentage-point margin of error, 39 percent of voters said investigating the president’s phone use — the subject of an Oct. 24 New York Times report — should be a must-do item for Congress. That’s 8 points higher than the share who prioritized investigating the Trump campaign’s potential ties to Russia during the 2016 presidential race.

Looking into Trump’s phone use and whether he was vulnerable to spying was the top priority for 40 percent of independents and 23 percent of Republicans, the highest for those two groups among any potential probes included in the survey.

Fifty-seven percent of Democrats also said the phone inquiry should be a top priority, although they were more interested in having members of Congress look into three other avenues. Those voters most want Congress to investigate Trump’s business interests and arrangements to determine whether they are conflicting with his duties as president (67 percent) and examine the administration’s family separation policy regarding migrants and the handling of unaccompanied minors (63 percent). They are also avid supporters of compelling Trump to release his tax returns (59 percent) — a 2016 campaign pledge that he has yet to honor.
