President Donald Trump is expected to sign executive orders Wednesday restricting access to the U.S. for refugees and some visa holders from terrorist hotbeds, according to a Reuters report Tuesday.

Reuters reported that congressional aides and immigration experts briefed on the matter say that refugees and some visa holders from Iraq, Iran, Libya, Somalia, Sudan, Syria and Yemen will be affected by the executive orders. The Refugee Act of 1980 and the Immigration and Nationality Act of 1952 give the president broad authority to limit immigration.

President Trump vowed to limit refugee entries from terrorist hotbeds during his campaign for the presidency. Since his inauguration, however, nearly 500 refugees have settled in the U.S.

An Associated Press report Tuesday contradicts the Reuters report and says that President Trump will sign executive orders regarding border security on Wednesday and orders regarding refugees later in the week.
