The Iraqi Prime Minister is expected to ask for increased military assistance from the United States, including drones and other weapons worth billions of dollars, according to various media reports.
A White House press release said that Abadi's visit would underscore "the strong US commitment to political and military cooperation with Iraq in the joint fight" against the ISIL.
On Monday, the US Defense Department said in a statement that up to 30 percent of the Iraqi territory seized by the ISIL had been retaken since the start of the air campaign.
Obama and Abadi will also discuss how Washington and Baghdad can expand political, commercial and cultural relations, as well as the Iraqi government's "actions to address the needs of the Iraqi people," according to the White House press release.
The two leaders held a bilateral meeting for the first time at the UN headquarters in New York shortly after Abadi assumed office in September 2014.
