President Donald Trump's campaign team has come under fire for their "Send A Brick" campaign.
The campaign urges people to pay $US20.20 to buy a brick, and send it to the offices of speaker of the house Nancy Pelosi, and senate minority leader Chuck Schumer, to reinforce Mr Trump's desire to build a wall along the border of the US and Mexico.
The website for the campaign allows users to "send Nancy a brick" or "send Chuck a brick", with an SMS number for people to donate to the cause.

There's also a photograph of a red brick that reads "2018: Fentanyl at the border. Enough entered U.S to kill every American."
President Trump's son, Donald Trump Jr. tweeted on Saturday "Since Chuck and Nancy keep stonewalling the President, why don't we send the wall to them, brick by brick, until they agree to secure the border?"
He then links the website.
However, users were quick to respond to the now deleted Tweet and point out that the campaign was a thinly veiled incitement of violence, and the funds were being directed mostly towards Mr Trump.
"This seems like a bad idea, no? Inviting people to send a brick to Chuck and Nancy's offices is likely to end with some nut hurling it through a window"
"As the fine print says, 'faux bricks will be sent to the offices of Chuck Schumer or Nancy Pelosi.' Then your dad is getting 75 percent of the money, and the GOP...interesting."
The user is correct - according to the campaign website, the proceeds will be going to the "joint fundraising committee composed of Donald J. Trump for President, Inc. and the Republican National Committee."
It continues to say that 75 percent of the money raised will go to Mr Trump "to be designated toward either its 2020 primary (which shall be the default) or 2020 general election."
Only 25 percent will go towards the Republican Party as a whole.
An analysis in the Washington Post shows that if Mr Trump wished to build his wall using this campaign, at $US20.20 a brick, it would cost $US58 billion.
The federal government has been shut down since December, as Mr Trump requests $US5 billion from the Democrats to build the wall.
