Anticipation is building for President Trump’s first State of the Union address after his tumultuous first year in office.

But the tickets for Tuesday’s event are already gaining attention.

On Monday, several lawmakers noticed an embarrassing spelling error on their blue invites: State of the Union was spelled “State of the Uniom.”

The tickets weren’t issued by the White House but rather by the Sergeant at Arms office, which performs a number of protocol and ceremonial duties in the House. The tickets will be reprinted and distribution will be delayed because of it, NBC News reported.

It’s not clear how many tickets had typos and how many will need to be recalled, according to CNN.

Some policymakers took the mistake in good humor, while others took the opportunity for a dig at the White House.

Sen. Marco Rubio of Florida tweeted, “Looking forward to tomorrow’s State of the Uniom.”

Meanwhile, Rep. Raul Grijavala tweeted, “Just received my ticket for the State of the Union. Looks like @BetsyDeVosEd was in charge of spell checking... #SOTUniom.”

Though the Sergeant at Arms office is responsible for this particular typo, spelling errors by the Trump administration have been relatively common. To name a few examples, the White House press release on Trump’s trip to Israel last spring said a goal for Trump was to “promote the possibility of lasting peach,” while Trump’s schedule has repeatedly misspelled British Prime Minister Theresa May’s name as “Teresa May.”
