Pelosi elected Speaker as Democrats take control of House of Representatives

Pelosi, a Democrat, sent the letter to the Republican president hours after being elected speaker of the House as the USA government was in the 13th day of a partial shutdown over Trump's demand for $5 billion for a border wall.

After recapturing the speaker's gavel, Pelosi vowed to pass six appropriations bills in the House to fund most of the government and a continuing resolution to fund the Department of Homeland Security (DHS) until February 8.

Republicans and Democrats have been squabbling over spending bills to keep about a quarter of the government running after hitting an impasse on Trump's demand to fund a border wall with Mexico.

The White House said ahead of the vote that Trump's advisors would recommend that the president veto the bill if it does not provide funding for the border wall.

Pelosi, who was elected speaker earlier Thursday, also took a shot a Trump, calling his proposal "a wall between reality and his constituents". "We are going to make it good".

Pelosi will preside over the most diverse Congress in history. How many more times can we say no?

Democrats also approved, 241-190, a separate measure funding the Agriculture, Interior and other departments through September 30. There are more women than ever before, and a new generation of Muslims, Latinos, Native Americans and African-Americans is creating a House more aligned with the population of the United States.

Pelosi remains firm on not funding Trump's border wall.

Democrats took control of the House of Representatives this week and elected Pelosi to a post she first held from 2007 to 2011.

The short-term bill for DHS passed the House 239-192, with five Republicans breaking ranks to join all Democrats in support of the bill.

The White House sent formal invitations to congressional leaders to meet late Friday morning, CBS News confirmed.

On Thursday Democratic committee chairs - newly vested with subpoena power - began to lay out their plans to investigate President Trump and his administration.

Trump, whose own bid for 2020 already is underway, faces potential challenges from the ranks of Senate Democrats under Chuck Schumer.

The video concludes with footage of Trump at the border along with audio from one of his rallies in which he vows to build his promised border wall and the crowd chants "Build the wall!"

Congress was re-opened on Thursday amid a government shutdown in the US.

In a nod to the historic nature of her election, Pelosi said she felt "particularly proud" to serve as "the woman speaker of the House of this Congress which marks the 100th year of women having the right to vote".

Some Republican senators have spoken out in favour of approving the funding bills, in order to end the government shutdown.

The largely party-line votes by the new Democratic majority came after Trump made a surprise appearance at the White House briefing room to pledge a continued fight for his signature campaign promise. People familiar with the session but not authorized to speak publicly described Trump as holding forth at length on a range of subjects but said he made clear he was firm in his demand for $5.6 billion in wall funding and in rejecting the Democrats' request to reopen the government.

The Republican-run Senate said it might not even vote on the legislation.
