Trump has pushed forward the building of the Keystone pipelines
The president’s action would be in line with his campaign promise to support Keystone XL and he would be reversing the Obama's administration rejection of the project.
Former president Barack Obama announced that he would reject the application to build the pipeline in November 2015.
Environmentalists have campaigned against the project for more than seven years; they fear that the pipelines will release climate-warming carbon into the atmosphere.
Mr Trump is due to sign the papers on Tuesday on just his fourth day in office.

Environmentalists have campaigned against the pipelines
It could carry up to 830,000 barrels of oil a day
The proposed pipeline would be 1,179 miles long and would run from the oil sands in Alberta, Canada to Steele City in Nebraska.
It could carry up to 830,000 barrels of oil a day and would allow for an increased supply of oil from Canada.
The pipeline has been controversial because of the risks of spillage and that it would mean a commitment to develop Alberta’s oil sands.
President Obama rejected the pipeline when he was in office
Many people have opposed the project because of the risk to local communities and the destruction of the local environment.
Republicans have supported the project because it would help thousands of Americans find work and it would increase the supply of North American energy.
Billionaire Trump hopes to give the oil industry more freedom to expand infrastructure and ease transportation bottlenecks.
