John Tyler assumed the presidency of the US when President William Henry Harrison died. On the last days of his presidency, Congress passed the joint resolution to annex Texas, the Republic of Texas voted to accept the annexation on June 23rd. On March 1st, the last day of his presidency, President Tyler signed the Joint Resolution for Texas Annexation.
He won a constitutional amendment that removed Congress's power to overturn vetoes.
And it’s Presidency, Have a good day.
