 Maguire subsequently drifted out of the IRA and became Vice-President of Sinn Fein from 1931-1933 during the Presidency of Brian O'Higgins.In 1932, a Mayo IRA officer reported that Maguire, now firmly aligned with Sinn Féin, refused to call on men to join the IRA when speaking at republican commemorations.When challenged on this, Maguire claimed that, as the IRA "were no longer the same as they used to be", he disagreed with the organisation.
