(CNN)Six months into his presidency, Donald Trump's overall approval rating stands at its lowest point in CNN polling, while three-quarters of Americans say they can't trust most of what they hear from the White House.

Overall, 38% say they approve of Trump's handling of the presidency, according to a new CNN poll conducted by SSRS, with 56% saying they disapprove. Just one other newly-elected president has held an approval rating below 50% at this point in his presidency since modern polling began: Bill Clinton, whose approval rating stood at 44% at this point in 1993.

Enthusiasm breaks against Trump by a 2-to-1 margin. Nearly half in the new poll say they strongly disapprove of Trump's handling of the job (47%), while just a quarter say they feel strongly positive about Trump's performance (24%).

Those numbers have soured in recent months, particularly among Trump's core supporters. Among Republicans, strong approval has dropped from 73% in February to 59% now. Among whites who do not have college degrees, a core component of Trump's base, just 35% strongly approve, down 12 points since February. At the same time, strong disapproval among Democrats has held steady around 80%.
