Trump rape case: After 3 years, the former president finally agrees to submit DNA. Here's why it could be too late.

Former President Donald Trump has agreed to undergo DNA testing in a civil rape trial in New York federal court.

The accuser, writer E. Jean Carroll, has been requesting a DNA sample from Trump for three years.

The court papers confirm that Trump is willing to provide a DNA sample for comparison to the DNA found on the dress in question.

Trump's lawyers are also demanding that the accuser provide the genome to be compared to.

The filing argues that if the alleged sexual assault never occurred, then Trump's DNA would not be on the dress.

The timeline for DNA testing has not been specified and it is unclear if the sample will be allowed as evidence in the case.

The deadline for exchanging evidence has already passed, and the judge has complained about Trump's side delaying the case.

The accuser and their lawyers would have to agree to the late evidence being admitted into the case.

The writer alleges that Trump raped her in a Bergdorf Goodman dressing room in the mid-1990s.

Lawyers for both sides have not commented on the recent developments.
