The senate failed to convict president johnson during his impeachment trial by how many votes?

On May 16, the Senate failed to convict Johnson on one of the articles, with the 35–19 vote in favor of conviction falling short of the necessary two-thirds majority by a single vote. A ten-day recess was called before attempting to convict him on additional articles. The delay did not change the outcome, however, as on May 26, it failed to convict the President on two articles, both by the same margin; after which the trial was adjourned.
