Washington (AFP) – The US Democrats, who regained control of the House of Representatives on Thursday, pledged to challenge Donald Trump on several fronts: Congressional investigations into electoral interference in Russia's battles over 39, immigration and health care, while rumors about the impeachment procedure persist.

The Congress will bring together the largest number of progressive lawmakers for many years and they do not seem willing to appease a president who remains firm in his quest for funding for a wall on the southern border of Mexico.

Under the leadership of President-elect Nancy Pelosi, Democrats will embark on the first day by proposing a bill to end a partial government shutdown and a separate measure to protect people's insurance coverage. presenting pre-existing health problems.

Republicans still retain control of the US Senate, but here are some key ways that newly empowered House Democrats can create all sorts of headaches for Trump:

– Investigations –

Following their victory in the November mid-term elections, the Democrats will assume the leadership of all House committees.

The new presidents said Trump would face a series of problems that could reveal alleged conflicts of interest, embezzlement and abuse of power by the president and members of his cabinet.

Additional investigations could spoil a white house already besieged by the investigation of special advocate Robert Mueller over Russia, draining the administration program's energy and thwarting Trump's message .

The chairman of the House Judiciary Committee, Jerrold Nadler, warned that he was planning to investigate the dismissal of Attorney General Jeff Sessions by Trump in November, an initiative that put at risk the Mueller probe.

Trump's tax returns, which he refused to make public during his campaign, will be at the top of the list. Pelosi said in October that requiring them "is one of the first things we would do."

– Immigration –

The issue of illegal immigration has fueled much of Trump's political agenda and his clashes with Democrats.

The president insists on funding $ 5 billion for the construction of a border wall that he says will help control undocumented migrants illegally entering the country. But the Democrats do not care.

When Trump threatened to veto any spending bill without the wall last month, several agencies stopped receiving funds, resulting in a partial closure of the government.

On Thursday, Pelosi will introduce two bills to fund the closed agencies, but said they "do not contain any new funding."

The White House has called Pelosi's plan a non-starter.

But on Tuesday, Trump openly asked if the Democrats were willing to negotiate.

"Let's make a deal?" he tweeted.

– Legislative obstacles –

A Democrat-led House will likely slow down Trump's legislative agenda. Their first major bill Thursday will include a major overhaul of election campaign funding as well as voting and ethics laws.

The bill may not be adopted by the Republican-held Senate, but it will be part of a democratic project for the year of the 2020 presidential elections.

The President will be facing an opposition party determined to champion the Affordable Care Act, the Obama – era health care reform that Republicans have repeatedly attempted to repeal.

Democrats will act early to protect people with a pre-existing illness, a popular feature of the Affordable Care Act that a Texas judge recently invalidated.

Democrats in the House make fun of Trump by putting the environment at the center of their concerns. They set up a new special committee on the climate crisis so that the government can better deal with the urgency of global warming.

– Threat of dismissal –

The threat of indictment will loom in the background of the new 116th Congress. It is almost certain that some Liberal Democrats will introduce procedures to dismiss the President.

Although Democrats believe that some of Trump's actions, including the payment of hidden sums to women during the 2016 campaign, erase the threshold of "serious crimes", Pelosi downplayed the chances of impeachment.

If the House succeeded in dismissing Trump, it would be difficult to remove him from office. He would need to be condemned by two-thirds of US senators – an unlikely prospect, unless members of his own Republican party attack him.
