Sen. Ted Cruz (R-Tex.) is now 100 percent American.

The tea party favorite announced last summer that he would takes steps to renounce his Canadian citizenship after the Dallas Morning News pointed out that he probably remained a citizen there by virtue of his birth.

As of May 14, Cruz was no longer a Canadian citizen.

His spokeswoman on Tuesday passed along a document from the Canadian government certifying that he ceased to be a citizen last month.

Cruz was born in Canada in 1970, to an American mother and Cuban father. Because of his mother's nationality, Cruz instantly became a U.S. citizen.

So that's the end of it, right? Well, not quite. The debate about whether Cruz can run for president because it's not 100 percent clear that he's a "natural-born citizen" will likely rage on.
