“She is going to have to specifically come to the Hill, talk about trying to get better relations between the departments and the Hill, and specifically answer questions about executive amnesty. Is it legal? Is it constitutional?” Barrasso said on “Fox News Sunday.”

Senate Democrats could try to approve her nomination in the lame-duck session, but Barrasso warned against it.

“We have not done an attorney general confirmation in a lame-duck since 1906 — and that was in the same party,” Barrasso said. “The last time we’ve done one with a change of party was when James Buchanan was leaving the White House and Abraham Lincoln was coming in. So as I say, what the president does in two months is very consequential for the next two years.”
