That is false. The official unemployment rate in May was 13.3%, but the BLS estimates it was under-stated by about 3% due to classification errors. That makes the “true” unemployment rate about 16.3% (not 20%, as you guess without any justification).

However, this rate is still down from last month. This same classification error was present in April:

If the workers who were recorded as employed but absent from work due to "other reasons" (over and above the number absent for other reasons in a typical April) had been classified as unemployed on temporary layoff, the overall unemployment rate would have been almost 5 percentage points higher than reported (on a not seasonally adjusted basis).

With an official unemployment rate of 14.7% in April, the “real” unemployment rate would be 19.7%.

The official unemployment rate fell from 14.7% to 13.3%. The “corrected” unemployment rate fell from ~19.7% to ~16.3%. It fell either way. You have 150,000 listening to you, you haveto do better than this.
