The People for the Ethical Treatment of Animals is launching a campaign to oust trophy hunter Donald Trump Jr. with strategically placed billboards.

PETA's latest ad states, "Deport Callous Cheating Opportunists Now," and features Don Jr. holding a knife in one hand and a bloodied, hacked-off elephant's tail in the other. The billboard will be placed in two locations along the border towns of El Paso and Laredo, Texas.

The prominently-featured photo was taken in 2012 during Don Jr.'s hunting spree in Africa.

The organization's warning of "undesirables" came on the heels of the president deploying National Guard troops along the Mexican border to police the area.

PETA released a statement on Friday admonishing Trump's eldest son.

While people are fleeing to the U.S. to escape violence, overprivileged, callous, cheating louts like Donald Trump Jr. are flying overseas to gun down living, feeling beings just for fun. PETA's border ad is a reminder that kindness is a virtue and that the true "bad hombres" are those killing animals for some sort of pathetic "sport.

Ingrid Newkirk, president of PETA and its other international affiliates tweeted, "VIOLENT, CRUEL, UNFAITHFUL, OPPORTUNISTIC. Factual description of this Undesirable who travels to foreign countries to shoot wildlife in cold blood in a pathetic display of "white Bwana complex" male insecurity. One day he'll get his come-uppance."

Don Jr. was boastful about being a hunter after controversial photos of him and his brother Eric posing with their kill from a 2012 trip to Africa were posted online.

In response to Eric and Don Jr. hunting and killing wildlife animals back in 2012 – including a crocodile, kudu, civet cat, leopard, and an elephant – PETA released this statement:

If the young Trumps are looking for a thrill, perhaps they should consider skydiving, bungee jumping, or even following in their anti-hunting father's footsteps and taking down competing businesses—not wild animals.

The organization pushed their aggressive stance against hunting by sending Huntsman Condoms to poachers around the world, including Eric and Don Jr., as an initiative to prevent hunters from reproducing.

PETA also demonstrated their solidarity with the Parkland high school students with a banner outside the organization's D.C. office, expressing they're against all forms of violence.

Newkirk tweeted, "Some people who SUPPORT assault weapons are excited that out of millions of PETA supporters one person did something awful."

Twitter lauded the campaign bashing the trophy hunter.
