Two House committees announced Friday that they are investigating potential violations of the Constitutions emoluments clauses by President Donald Trump , Vice President Mike Pence and others in the Trump administration .

House Oversight Committee Chairman Elijah Cummings (D-Md.) sent four letters requesting itemized costs and other documentation regarding Pences controversial stay this week at the Trump International Golf Links and Hotel in Doonbeg, Ireland.

Whether Trump violated the Constitution by suggesting the next Group of Seven summit be held at his Miami resort , Trump National Doral, is the subject of a separate inquiry by the House Judiciary Committee.

The vice president was forced to defend his decision to stay at Trumps Irish resort, saying Tuesday that it was close to his ancestral hometown. (Pence is of Irish descent.) Critics maintained that the resort was not at all convenient for Pences purposes, as it is 180 miles from Dublin, where the vice president was meeting with Irish leaders.

The oversight committee also asked for information about the presidents stay at the same resort in June, which prompted similar questions over whether Trump was using the presidency to enrich himself, against the Constitution. Trumps post-London detour to his Irish golf course ran up a tab of $3.6 million , footed by American taxpayers.

The Committee does not believe that U.S. taxpayer funds should be used to personally enrich President Trump, his family, and his companies, Cummings wrote in Fridays letters.

House Judiciary Chairman Jerry Nadler (D-N.Y.) and Rep. Steve Cohen (D-Tenn.), chairman of the Subcommittee on the Constitution, Civil Rights and Civil Liberties, also voiced concerns about Trump soliciting foreign business to his properties particularly when he floated the use of his Miami resort for the next G-7 summit.
