Though no evidence has been offered to back President Trump's baseless claim that former President Barack Obama wiretapped his phones at Trump Tower during the presidential election, an overwhelming majority of Republicans think it's likely. A CBS News poll released Wednesday found that 74 percent of Republicans believe it's "very likely" or "somewhat likely" that Trump's offices were wiretapped. Just 21 percent of Democrats think it's a possibility, while 49 percent of independents deemed it likely.
When Trump leveled the allegation on Twitter weeks ago, he offered no supporting evidence, and he has yet to come forward with any as he's continued to defend the claim. House Speaker Paul Ryan (R-Wis.), the Senate and House Intelligence Committees, the Justice Department, and FBI Director James Comey have all said they have not uncovered any evidence whatsoever that backs Trump's allegation. Comey even noted during a hearing before the House Intelligence Committee earlier this month that it's impossible for a president to "unilaterally" order a wiretap, as Trump has claimed Obama did.
The poll was conducted by phone from March 25-28 among 1,088 adults. Its margin of error for the entire sample is plus or minus 4 percentage points.
