More broadly, support for Trump's deportation program has declined in recent months. Sunday's poll found that 51 percent of respondents disapprove of the program, while 49 percent approve. That marks a notable drop from a similar February poll, when 59 percent approved, and from 54 percent in a June poll.

June 23 -16: Trump’s approval rating dipped one point, to 41%, in a Reuters/Ipsos survey of 1,139 U.S. adults taken June 21-23 from its June 11-16 survey, with 57% disapproving (the latest poll has a 3-point margin of error).
