The U.S. Senate confirmed Treasury Secretary nominee Steven Mnuchin Monday night, despite objections to the former by Democrats.

Meanwhile the vote to confirm Dr. David Shulkin as VA secretary was unanimous in his favor.

The Senate held several hours of debate for Mnuchin Monday, in which Democrats strongly objected to his role in the 2008 housing crisis.

The final vote was 53-47, with West Virginia Sen. Joe Manchin the only Democrat voting in favor.

Mnuchin's a former Goldman Sachs executive. He also bought and helped turn around the former IndyMac Bank, renaming it OneWest. The bank was accused of aggressive foreclosures on struggling homeowners, including elderly homeowners and members of the military. 

The Senate voted party line for Mnuchin's confirmation, with Sen. Bill Nelson, D-FL voting against Mnuchin and Sen. Marco Rubio, R-Florida voting for him.

President Trump swore Mnuchin in Monday night.

Shulkin was also confirmed as VA secretary nominee. Shulkin is a former Obama administration officials who served as the Veterans Affairs Dept.'s top health official since 2015. He is not a member of the military, making him the first VA secretary who was not a veteran.

However, he has strong backing from Democrats after ruling out fully privatizing the VA and saying wide-scale firings of VA employees were unnecessary, thus disagreeing with President Trump.

Shulkin will be sworn in on Tuesday.

The Senate is also expected to vote on Linda McMahon's confirmation as Small Business Administration head on Tuesday.

On Thursday the Health, Education, Labor and Pensions committee is expected to finally take up the nomination of Andy Puzder as Labor Secretary. Sources with in the Senate say at least four Republican senators may vote against Puzder, putting his nomination in jeopardy.
